TVP5158, TVP5157, TVP5156 www.ti.com 1.2 • • • • SLES243G – JULY 2009 – REVISED APRIL 2013 Applications Security and surveillance digital video recorders or servers and PCI products Automotive infotainment video hub Large format video wall displays Game systems 1.3 Description The TVP5158, TVP5157, and TVP5156 devices are 4-channel high-quality NTSC/PAL video decoders that digitize and decode all popular base-band analog video formats into digital video output. Each channel of this decoder includes 10-bit 27-MSPS A/D converter (ADC). Preceding each ADC in the device, the corresponding analog channel contains an analog circuit that clamps the input to a reference voltage and applies the gain. Composite input signal is sampled at 2x the ITU-R BT.601 clock frequency, line-locked alignment, and is then decimated to the 1x pixel rate. CVBS decoding uses five-line adaptive comb filtering for both the luma and chroma data paths to reduce both cross-luma and cross-chroma artifacts. A chroma trap filter is also available. On CVBS inputs, the user can control video characteristics such as contrast, brightness, saturation, and hue via an I2C host port interface. Furthermore, luma peaking (sharpness) with programmable gain is included. All four channels are independently controllable. These decoders share a single clock input for all channels and for all supported standards. TVP5158 provides a glueless audio and video interface to TI DaVinci™ video processors. Video output ports support 8-bit ITU-R BT.656 and 16-bit 4:2:2 YCbCr with embedded synchronization. TVP5158 supports multiplexed pixel-interleaved and line-interleaved mode video outputs with metadata insertion. TVP5158 and TVP5157 integrate 4-Ch audio ADCs to reduce the BOM cost for surveillance market. Multiple TVP5158 devices can be cascade connected to support up to 8-Ch Video or 16-Ch audio processing. Noise reduction and auto contrast functions improve the video quality under low light condition which is very critical for surveillance products. The TVP5158, TVP5157, and TVP5156 can be programmed by using a single I2C serial interface. I2C commands can be sent to one or more decoder cores simultaneously, reducing the amount of I2C activity necessary to configure each core. This is especially useful for fast downloading modified firmware to the decoder cores. TVP5158, TVP5157, and TVP5156 use 1.1-V, 1.8-V, and 3.3-V power supplies for the analog/digital core and I/O. These devices are available in a 128-pin TQFP package. Table 1-1.

Figure 3-1 shows the video analog processing and ADC block diagram. Analog CVBS Input Anti-Aliasing Filter Output to Digital Processing ADC Clamp Reference & Bias Figure 3-1. Video Analog Processing and ADC Block Diagram 3.1.1 Analog Video Input Supports NTSC (J, M, 4.43) and PAL (B, D, G, H, I, M, N, Nc, 60) video standards. Each video decoder channel supports a composite video input with a pseudo-differential pin which improves the noise immunity and analog performance. Each video decoder input should be ac-coupled through a 0.1-µF capacitor. The nominal parallel termination resistor before the input to the device is 75 Ω. Each video decoder integrates an anti-aliasing filter to provide good stop-band rejection on the analog video input signal. Figure 3-2 shows the frequency response of the anti-aliasing filter.

The dc restoration circuit (sync-tip clamp) restores sync-tip level of the ac-coupled composite video signal to a fixed dc level near the bottom of the A/D converter range. 3.1.3 A/D Converter All ADCs have a resolution of 10 bits and can operate at 27 MSPS. Each A/D channel receives a clock from the on-chip phase-locked loop (PLL) at a nominal frequency of 27 MHz. All ADC reference voltages are generated internally. 3.2 Digital Video Processing Digital Video Processing block receives digitized video signals from the ADCs and performs composite processing and YCbCr signal enhancements. The digital data output can be programmed to two formats: ITU-R BT.656 8-bit 4:2:2 with embedded syncs or 16-bit 4:2:2 with embedded syncs. The circuit also detects pseudo-sync pulses, AGC pulses, and color striping in Macrovision-encoded copy-protected material. 3.2.1 2x Decimation Filter All input signals are over-sampled by a factor of 2 (by 27-MHz clock). The A/D outputs initially pass through decimation filters that reduce the data rate to 1x the pixel rate. The decimation filter is a half-band filter. Over-sampling and decimation filtering can effectively increase the overall signal-to-noise ratio by 3 dB. 3.2.2 Automatic Gain Control The automatic gain control (AGC) can be enabled and can adjust the signal amplitude controlled by 14-bit digital gain stage after the ADC. The AGC algorithms can use up to four amplitude references: sync height, color burst amplitude, composite peak, and luma peak. The specific amplitude references being used by the AGC algorithms can be controlled using the AGC white peak processing register located at subaddress 2Dh. The gain increment speed and gain increment delay can be controlled using the AGC increment speed register located at subaddress 29h and the AGC increment delay register located at subaddress 2Ah. The gain decrement speed and gain decrement delay can be controlled using the AGC decrement speed register located at subaddress 2Bh and the AGC decrement delay register located at subaddress 2Ch. 3.2.3 Composite Processor This Composite Processor circuit receives a digitized composite signal from the ADCs and performs sync and Y/C separation, chroma demodulation for PAL/NTSC, and YUV signal enhancements. The slice levels of the sync separator are adaptive. The slice levels continually adapt to changes in the back-porch and sync-tip levels. The 10-bit composite video is multiplied by the sub carrier signals in the quadrature demodulator to generate U and V color difference signals. The U and V signals are then sent to low-pass filters to achieve the desired bandwidth. An adaptive 5-line comb filter separates UV from Y based on the unique property of color phase shifts from line to line. The chroma is re-modulated through a quadrature modulator and subtracted from line-delayed composite video to generate luma. This form of Y/C separation is completely complementary, thus there is no loss of information. However, in some applications, it is desirable to limit the U/V bandwidth to avoid crosstalk. In that case, notch filters can be turned on. To accommodate some viewing preferences, a peaking filter is also available in the luma path. Contrast, brightness, sharpness, hue, and saturation controls are programmable through the I2C host port. Figure 3-3 shows the block diagram of Composite Processor. 16 Functional Description Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TVP5158 TVP5157 TVP5156 TVP5158, TVP5157, TVP5156 www.ti.com CVBS SLES243G – JULY 2009 – REVISED APRIL 2013 Line Delay Delay Peaking Y NTSC/PAL Remodulation Y Contrast Notch Notch Filter Filter Brightness Saturation Adjust Cr Color LPF 2 Cb Burst Accumulator (U) 5 Line Adaptive CVBS NTSC/PAL Demodulation Color LPF 2 Burst Accumulator (V) Comb Filter Notch Filter Delay Notch Filter Delay U V Figure 3-3. Composite Processor Block Diagram 3.2.3.1 Color Low-Pass Filter High filter bandwidth preserves sharp color transitions and produces crisp color boundaries. However, for nonstandard video sources that have asymmetrical U and V side bands, it is desirable to limit the filter bandwidth to avoid UV crosstalk. The color low-pass filter bandwidth is programmable to enable one of the three notch filters. Figure 3-4 and Figure 3-5 represent the frequency responses of the wideband color low-pass filters.

Color Low-Pass Filter with Filter Characteristics, NTSC/PAL ITU-R BT.601 Sampling 3.2.3.2 Y/C Separation Y/C separation can be done using adaptive 5-line (5-H delay) comb filters or a chroma trap filter. The comb filter can be selectively bypassed in the luma or chroma path. If the comb filter is bypassed in the luma path, then chroma trap filters are used which are shown in Figure 3-6 and Figure 3-7. The TI patented adaptive comb filter algorithm reduces artifacts such as hanging dots at color boundaries. It detects and properly handles false colors in high-frequency luminance images such as a multiburst pattern or circle pattern. 18 Functional Description Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TVP5158 TVP5157 TVP5156 TVP5158, TVP5157, TVP5156 www.ti.com SLES243G – JULY 2009 – REVISED APRIL 2013 Figure 3-6.

Chroma Trap Filter Frequency Response, PAL ITU-R BT.601 Sampling 3.2.4 Luminance Processing The digitized composite video signal passes through either a luminance comb filter or a chroma trap filter, either of which removes chrominance information from the composite signal to generate a luminance signal. The luminance signal is then fed into the input of a peaking circuit. Figure 3-8 shows the basic functions of the luminance data path. A peaking filter (edge enhancer) amplifies high-frequency components of the luminance signal. Figure 3-9 shows the characteristics of the peaking filter at four different gain settings that are user-programmable via the I2C interface.

Peaking Filter Response, NTSC/PAL ITU-R BT.601 Sampling 3.3 AVID Cropping AVID or active video cropping provides a means to decrease the amount of video data output. This is accomplished by horizontally blanking a number of AVID pulses and by vertically blanking a number of lines per frame. Horizontal cropping can be enabled/disabled using bit-6 of address B1h. When line cropping is enabled, active video is reduced from 720 to 704 pixels for unscaled video and from 360 to 352 pixels for down-scaled video. When line cropping is enabled, the TVP5158 crops an equal amount from both the start and end of active video. Register 8Ch can be used to delay both the start and end of active video. It allows selecting which 704 pixels out of 720 are actually being used for active video when line cropping is enabled. 3.4 Embedded Syncs Standards with embedded syncs insert SAV and EAV codes into the data stream at the beginning and end of horizontal blanking. These codes contain the V and F bits which also define vertical timing. F and V change on EAV. Table 3-1 gives the format of the SAV and EAV codes. H equals 1 always indicates EAV. H equals 0 always indicates SAV. The alignment of V and F to the line and field counter varies depending on the standard. Please refer to ITU-R BT.656 for more information on embedded syncs. The P bits are protection bits: P3 = V xor H P2 = F xor H P1 = F xor V P0 = F xor V xor H Table 3-1.

Human eyes are very sensitive to oscillating signals, the visual quality degenerates significantly even when the noise level is small. Each video decoder uses a TI proprietary spatial filter to reduce video noise. For each frame of image, the video noise filter (VNF) produces an estimate of the Y/U/V noise. Based on the noise estimates, the firmware adjusts the threshold for Y/U/V filtering. The filtered video shows improved video quality and lower compression bit-rate. The firmware can also utilize the Y/U/V noise estimates to make decisions to disable color if the video noise is determined to be too high. This "color killer" decision bit can be used to control another module that implements the color killing function. The Noise Reduction can be controlled using I2C registers from 5Ch to 5Fh. This module can also be set to bypass mode by I2C register 5Dh (Bit 0). 3.7 Auto Contrast The Auto Contrast (AC) module can adjust the picture brightness automatically or manually (user programmable) for better image quality. The goal of AC processing is to make the dark area brighter and high-light area dimmer. This makes it possible for the viewer to see details hidden in the shadows. It also prevents loss of details in the washed-out high light area. The AC processing is mostly for video surveillance applications. For each frame of image, the auto contrast module collects the statistics of its Y (luminance) values. The AC algorithm implemented in the firmware processes the statistics and generates a look-up table (LUT). This LUT is used to map each incoming pixel Y value to an output pixel Y value for the next frame of image. The LUT is updated during the blanking period between two frames. The Auto Contrast Mode can be controlled by using I2C registers 0Fh. This module can also be set to disable mode by I2C register 0Fh (Bit 1:0).

Table 3-4 provides a summary of line frequencies, data rates, and pixel counts for different input standards. TVP5158 supports non-interleaved output mode, pixel-interleaved output mode and line-interleaved output mode. The noninterleaved mode is similar to the TVP5154A device, except that a single fixed clock output is used. In the interleaved modes, the video output data from multiple decoder channels are multiplexed together and then output to a single 8-bit or 16-bit port. The video output data from selected channels can be interleaved on a pixel or line basis. Table 3-4.

Depending on which output mode is selected, the output for each channel can be unscaled data or scaled data. Also each video output port can be selected to output the video data from any 1 of 4 video decoders. Table 3-5 shows the detailed information about non-interleaved mode. Table 3-5.

In the line-interleaved mode, the video channels are multiplexed together on a line-by-line basis. Compared to the pixel-interleaved mode, the line-interleaved mode significantly reduces the code complexity and MIPS consumption of the backend processor. The 8-Ch modes require connecting two TVP5158 devices together using a video cascade interface (see Section 3.8.3.3). The TVP5158 also supports different image resolutions (for example, D1, Half-D1, and CIF) in the line-interleaved mode. All supported line-interleaved modes are shown in Table 310. Table 3-10.

The video output data with D1 resolution from any two video channels is multiplexed together on a line basis. The output ports DVO_A and DVO_B are used in this mode. The output clock OCLK_P is synchronized with both output ports.

The output resolution of video data can be D1, Half-D1 or CIF. For D1 and Half-D1 output resolutions, the video output port can be configured to support 8-bit BT.656 or 16-Bit YCbCr 4:2:2 data with embedded sync. Port DVO_A is used for 8-bit output. Ports DVO_A and DVO_B are used for 16-Bit output. The output clock OCLK_P is synchronized with all four output ports. TVP5158 supports multiplexing 4-Ch CIF and 1-Ch D1 data together and then output through DVO_A at 54 MHz. 1-Ch D1 can be from any one of 4 video channels. In typical surveillance applications, CIF resolution is used for recording and D1 resolution is used for video preview. TVP5158 also supports multiplexing 4-Ch Half-D1 and 1-Ch D1 data together and then output through DVO_A at 108 MHz. The backend chip can use Half-D1 to generate CIF format by dropped one field. Pleas note that the line-interleaved mode does NOT strictly output one line from each decoder channel sequentially. The order of multiplexed the video line data is based on the availability of video output data from each decoder channel. Therefore, it is possible to output two consecutive lines from the same decoder channel or to skip one decoder channel output. 3.8.3.3 8-Ch Line-Interleaved Mode Two TVP5158 devices can be cascade connected and work as single 8-Ch video decoder. In cascade mode, the port DVO_C and DVO_D of master TVP5158 (first stage) can be configured as the video input interface. The DVO_A and DVO_B of master TVP5158 are configured as the output interface for two devices. This mode is dedicated for the backend chip with extremely limited input ports. In the video cascade mode, the open-drain interrupt request (INTREQ) outputs from the first and second stages can be combined using a wired-OR connection. Typical applications with cascade mode show in the following diagrams. Figure 3-12 shows the Cascade Connection for 16-Ch CIF Recoding and Multi-Ch CIF Preview. Figure 3-13 shows the Cascade Connection for 16-Ch CIF Recoding and Multi-Ch Half-D1 Preview.

Cascade Connection for 16-Ch CIF Recoding and 2-Ch D1/Multi-Ch CIF Preview 3.8.3.4 Hybrid Modes The TVP5158 also supports multiplexing both scaled and unscaled data streams in the line-interleaved mode. In these hybrid modes (4-Ch Half-D1 + 1-Ch D1, 4-Ch CIF + 1-Ch D1, and 8-Ch CIF + 1-Ch D1), the D1 line is split into two equal-length half lines and then multiplexed with the other CIF lines. Therefore, all video data is actually multiplexed by CIF line length. In these hybrid modes, the line cropping mode affects both the scaled and unscaled data streams. The line cropping mode is controlled by bit 6 of I2C register B1h. 3.8.3.5 Metadata Insertion for Line-Interleaved Mode In the line-interleaved mode, the video data is rearranged on a line-by-line basis. There can be no guaranteed output line order, because all analog video inputs are not synchronized. To be compatible with general backend BT.656 decoder, the video data is encapsulated on TVP5158 output so that all input data is preserved and output data is understandable to a BT.656 decoder. To prevent confusion over image line count and vertical blanking appearing haphazardly, SAV/EAV codes have FID and V data stripped and replaced with FID = V = 0. Because vertical blanking in the input is being masked out, artificial vertical sync is inserted every encapsulated frame (a.k.a., super frame). Thus, to the unaware BT.656 decoder, the stream appears to be progressive data with two lines of vertical blanking. The default super-frame format and timing for each line-interleaved output format is shown in Table 3-11. 28 Functional Description Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TVP5158 TVP5157 TVP5156 TVP5158, TVP5157, TVP5156 www.ti.com SLES243G – JULY 2009 – REVISED APRIL 2013 Table 3-11.

The input pins I2CA0, I2CA1 and I2CA2 are used to select the slave address to which the device responds. Although the I2C system can be multi-mastered, the TVP5158 decoder functions as a slave device only. Both SDA and SCL must be connected to IOVDD via pullup resistors. When the bus is free, both lines are high. The slave address select terminals (I2CA0, I2CA1 and I2CA2) enable the use of up to eight devices on the same I2C bus. At the trailing edge of reset, the status of the I2CA0, I2CA1 and I2CA2 lines are sampled to determine the device address used. Table 3-16 summarizes the terminal functions of the I2C host interface. Table 3-17 shows the device address selection options. Table 3-16.

The number of devices connected to the bus is dependent on the bus capacitance limit of 400 pF. The data on the SDA line must be stable during the high period of the SCL except for start and stop conditions. The high or low state of the data line can only change with the clock signal on the SCL line being low. A high-to-low transition on the SDA line while the SCL is high indicates an I2C start condition. A low-to-high transition on the SDA line while the SCL is high indicates an I2C stop condition. Every byte placed on the SDA must be 8 bits long. The number of bytes which can be transferred is unrestricted. Each byte must be followed by an acknowledge bit. The acknowledge-related clock pulse is generated by the I2C master. To simplify programming of each of the 4 decoder channels a single I2C write transaction can be transmitted to any one or more of the 4 cores in parallel. This reduces the time required to download firmware or to configure the device when all channels are to be configured in the same manner. It also enables the addresses for all registers to be common across all decoders. I2C subaddress FEh contains 4 bits with each bit corresponding to one of the decoder cores. If a decoder write enable bit is set, then I2C write transactions are sent to the corresponding decoder core. For multibyte I2C write transactions, there are options to auto-increment the subaddress or to auto-increment through the selected decoders or both. 36 Functional Description Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TVP5158 TVP5157 TVP5156 TVP5158, TVP5157, TVP5156 www.ti.com SLES243G – JULY 2009 – REVISED APRIL 2013 I2C subaddress FFh contains 4 bits with each bit corresponding to one of the decoder cores. If a decoder read enable bit is set, then I2C read transactions are sent to the corresponding decoder core. If more than one decoder is enabled for reads, then the lowest numbered decoder that is enabled responds to the read transaction. For multi-byte I2C read transactions, there are options to auto-increment the subaddress or to auto-increment through the selected decoders or both. 3.10.1 I2C Write Operation Data transfers occur utilizing the following formats. An I2C master initiates a write operation to the decoder by generating a start condition (S) followed by the decoder I2C address (as shown below), in MSB first bit order, followed by a 0 to indicate a write cycle. After receiving an acknowledge from the decoder, the master presents the subaddress of the register, or the first of a block of registers it wants to write, followed by one or more bytes of data, MSB first. The decoder acknowledges each byte after completion of each transfer. The I2C master terminates the write operation by generating a stop condition (P).

The first phase is the address phase. In this phase, an I2C master initiates a write operation to the decoder by generating a start condition (S) followed by the decoder slave address, in MSB first bit order, followed by a 0 to indicate a write cycle. After receiving acknowledge from the decoder, the master presents the subaddress of the register or the first of a block of registers it wants to read. After the cycle is acknowledged, the master has the option of generating a stop condition or not. In the data phase, an I2C master initiates a read operation to the decoder by generating a start condition followed by the decoder I2C slave address (as shown below for a read operation), in MSB first bit order, followed by a 1 to indicate a read cycle. After an acknowledge from the decoder, the I2C master receives one or more bytes of data from the decoder. The I2C master acknowledges the transfer at the end of each byte. After the last data byte has been transferred from the decoder, the master generates a not acknowledge followed by a stop.

A crystal can be connected across terminals 99 (XTAL_IN) and 101 (XTAL_OUT), or a 1.8-V external clock input can be connected to terminal 99. Four horizontal PLLs generate the line-locked sample clock for each video decoder core from the system clock. Four color PLLs generate the color subcarrier frequency for each video decoder core from the corresponding line-locked clock. Four vertical PLLs generate the field/frame sync for each video decoder core. A frequency synthesizer generates the 32.768-MHz audio oversampling clock for each analog audio input from the system clock. Figure 3-21 shows the reference clock configurations. For the example crystal circuit shown, the external capacitors must have the following relationship: CL1 = CL2 = 2CL – CSTRAY Where, CSTRAY is the terminal capacitance with respect to ground CL is the crystal load capacitance specified by the crystal manufacturer 27-MHz Crystal 0W VSSA 27-MHz CLK Output to other TVP5158 XTAL_IN pin 27-MHz CLK Output to other TVP5158 XTAL_IN pin Figure 3-21.

Table 3-18 shows the configuration of reset mode. Table 3-19 describes the status of the decoder signals during and immediately after reset. Figure 3-22 shows the reset timing. After power-up, the device is in an unknown state until properly reset. An active-low reset, Reset B, of greater than or equal to 20 ms is required following active and stable supply ramp-up. To avoid potential I2C issues, keep SCL and SDA inactive (high) for at least 260 µs after reset goes high. There are no power sequencing requirements except that all power supplies should become active and stable within 500 ms of each other. Table 3-18.

Communication between the external controller and the decoder is through I2C. Table 4-1 shows the summary of these registers. The reserved registers must not be written. Reserved bits in the defined registers must be written with 0s, unless otherwise noted. The detailed programming information of each register is described in the following sections. I2C register FEh controls which of the four decoders will receive I2C commands. I2C register FFh controls which decoder core responds to I2C reads. Note that for a read operation, it is necessary to perform a write first to set the desired subaddress for reading. Compared to previous video decoder, TVP5154A, the TVP5158, TVP5157, and TVP5156 add decoder auto increment and address auto increment bits control. If decoder auto increment bit is set, the next read/write is from/to the next decoder that is enabled. If address auto-increment bit is set, the address increments after all the decoders enabled read/writes are completed. The detail of I2C registers FEh and FFh is shown in their register section.

Because this register is a multi-byte register, it is necessary to "capture" the setting into the register to ensure that the value is not updated between reading the lower and upper bytes. To cause this register to "capture" the current settings bit 0 of I2C register 24h (Status Request) should be set to a 1. After the internal processor has updated this register, bit 0 of register 24h is cleared, indicating that both bytes of the AGC gain status register have been updated and can be read. Either byte may be read first, because no further update occurs until bit 0 of 24h is set to 1 again. Table 4-26.

Status Request Subaddress Default 7 24h 00h 6 5 4 Reserved 3 Capture Setting a 1 in this register causes the inter processor to capture the current settings of the AGC status, noise measurement, and the vertical line count registers. Because this capture is not immediate, it is necessary to check for completion of the capture by reading the "capture" bit repeatedly after setting it and waiting for it to be cleared by the internal processor. After the "capture" bit is 0, the AGC status, noise measurement, and vertical line counters (20h/21h, 94h/95h, and A2h/A3h) have been updated, and can be safely read in any order. Table 4-28.

Audio Input Connectivity 6.5 Designing with PowerPAD™ Devices The TVP5158 device is housed in a high-performance, thermally enhanced, 128-terminal PowerPAD package. Use of the PowerPAD package does not require any special considerations except to note that the thermal pad, which is an exposed die pad on the bottom of the device, is a metallic thermal and electrical conductor. Therefore, if not implementing the PowerPAD PCB features, the use of solder masks (or other assembly techniques) can be required to prevent any inadvertent shorting by the exposed thermal pad of connection etches or vias under the package. The recommended option, however, is not to run any etches or signal vias under the device, but to have only a grounded thermal land as in the following explanation. Although the actual size of the exposed die pad may vary, the minimum size required for the keep-out area for the 128-terminal PFP PowerPAD package is 9mm x 9mm. It is recommended that there be a thermal land, which is an area of solder-tinned-copper, underneath the PowerPAD package. The thermal land varies in size, depending on the PowerPAD package being used, the PCB construction, and the amount of heat that needs to be removed. In addition, the thermal land may or may not contain numerous thermal vias depending on PCB construction. Other requirements for using thermal lands and thermal vias are detailed in the TI application note PowerPAD Thermally Enhanced Package application report (SLMA002). For the TVP5158 device, this thermal land must be grounded to the low-impedance ground plane of the device. This improves not only thermal performance but also the electrical grounding of the device. It is also recommended that the device ground terminal landing pads be connected directly to the grounded thermal land. The land size should be as large as possible without shorting device signal terminals. The thermal land can be soldered to the exposed thermal pad using standard reflow soldering techniques. While the thermal land can be electrically floated and configured to remove heat to an external heat sink, it is recommended that the thermal land be connected to the low-impedance ground plane for the device. More information can be obtained from the TI application note PHY Layout (SLLA020). 100 Application Information Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TVP5158 TVP5157 TVP5156 TVP5158, TVP5157, TVP5156 www.ti.com SLES243G – JULY 2009 – REVISED APRIL 2013 Revision History NOTE: Page numbers for previous revisions may differ from page numbers in the current version.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
