DESCRIPTION The DLPC350 digital controller, part of the DLP 0.45 WXGA chip set, supports reliable operation of the DLP4500 DMD, or Digital Micromirror Device. The DLPC350 controller provides a convenient, multi-functional interface between user electronics and the DMD, enabling high-speed pattern rates, providing LED control and data formatting for multiple input resolutions. The DLPC350 also outputs a trigger signal for synchronizing displayed patterns with a camera, sensor, or other peripherals. The DLPC350 controller enables integration of the DLP 0.45 WXGA chip set into small-form-factor and low-cost light steering applications. Example applications for the 0.45 WXGA chip set include 3D scanning or metrology systems with structured light, interactive displays, chemical analyzers, medical instruments, and other end equipment requiring spatial light modulation (light steering and patterning). The DLPC350 is one of the two devices in the 0.45 WXGA chip set (see Figure 1). The other device is the DLP4500 DMD. Search the TI Website for 'DLPR350' for additional information, and see the 0.45 WXGA ChipSet data sheet DLPU009 for further details. 2 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: DLPC350 DLPC350 www.ti.com DLPS029A – APRIL 2013 – REVISED MAY 2013 BLOCK DIAGRAM Figure 1. Chip Set Block Diagram In DLP-based solutions, image data is 100% digital from the DLPC350 input port to the image on the DMD. The image stays in digital form and is not converted into an analog signal. The DLPC350 processes the digital input image and converts the data into a format needed by the DLP4500. The DLP4500 steers light by using binary pulse-width-modulation (PWM) for each micromirror. Refer to DLP4500 Data Sheet (TI literature number DLPS028) for further details. Figure 2 is the DLPC350 functional block diagram. As part of the pixel processing functions, the DLPC350 offers format conversion functions: chroma interpolation and color-space conversion. The DLPC350 also offers several image-enhancement functions. The DLPC350 also supports the necessary functions to format the input data to the DMD. The pixel processing functions allow the DLPC350 and DLP4500 to support a wide variety of resolutions including NTSC, PAL, XGA, and WXGA. The pixel processing functions can be optionally bypassed with the native 912 × 1140 pixel resolution to support direct one-to-one pixel mapping. Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: DLPC350 3 DLPC350 DLPS029A – APRIL 2013 – REVISED MAY 2013 www.ti.com When accurate pattern display is needed, the native 912 x 1140 input resolution pattern has a one-to-one association with the corresponding micromirror on the DLP4500. The DLPC350 enables high-speed display of these patterns. This functionality is well-suited for techniques such as structured light, additive manufacturing, or digital exposure. Figure 2. DLPC350 Functional Block Diagram Commands can be input to the DLPC350 over an I2C interface. The DLPC350 takes as input 24-, 27- or 30-bit RGB data at up to 120-Hz frame rate. This frame rate is composed of three colors (red, green, and blue) with each color equally divided in the 120-Hz frame rate. Thus, each color has a 2.78 ms time slot allocated. Because each color has an 8-, 9-, or 10-bit depth, each color time slot is further divided into bit-planes. A bit-plane is the 2-dimensional arrangement of one-bit extracted from all the pixels in the full color 2D image to implement dynamic depth. See Figure 3. 4 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: DLPC350 DLPC350 www.ti.com DLPS029A – APRIL 2013 – REVISED MAY 2013 8-bit Red Image 8 Red Bit-Planes 8-bit Green Image 24-bit RGB Image 8 Green Bit-Planes 8-bit Blue Image 8 Blue Bit-Planes Figure 3. Bit Slices The length of each bit-plane in the time slot is weighted by the corresponding power of two of its binary representation. This provides a binary pulse-width modulation of the image. For example, a 24-bit RGB input has three colors with 8-bit depth each. Each color time slot is divided into eight bit-planes, with the sum of the weight of all bit planes in the time slot equal to 256. See Figure 4 for an illustration of this partition of the bits in a frame. b1 b 3 b0 b2 bit 4 16 bit 5 32 bit 6 bit 7 bit plane 64 128 256 Figure 4. Bit Partition in a Frame for an 8-Bit Color Therefore, a single video frame is composed of a series of bit-planes. Because the DMD mirrors can be either on or off, an image is created by turning on the mirrors corresponding to the bit set in a bit-plane. With binary pulsewidth modulation, the intensity level of the color is reproduced by controlling the amount of time the mirror is on. For a 24-bit RGB frame image inputted to the DLPC350, the DLPC350 creates 24 bit planes, stores them in a double-buffered eDRAM embedded in the chip, and sends them to the DLP4500 DMD, one bit-plane at a time. Depending on the bit weight of the bit-plane, the DLPC350 controls the time this bit-plane is illuminated, controlling the intensity of the bit-plane. To improve image quality in video frames, these bit-planes, time slots, and color frames are shuffled and interleaved with spatial-temporal algorithms by the DLPC350.

The bit-depth of the pattern is then allocated into the corresponding time slots. Furthermore, an output trigger signal is also synchronized with these time slots to indicate when the image is displayed. For structured light applications, this mechanism provides the capability to display a set of patterns and signal a camera to capture these patterns overlaid on an object. The DLPC350 stores two 24-bit frames in its internal memory buffer. This 48 bit-plane display buffer allows the DLPC350 to send one 24-bit buffer to the DMD array while the second buffer is filled from Flash or streamed in through the 24-bit RGB interface. In streaming mode, the DMD array displays the previous 24-bit frame while the current frame fills the second 24-bit frame of the display buffer. Once a 24-bit frame is displayed, the buffer rotates accessing the next 24-bit frame to the DMD. Thus, the displayed image is a 24-bit frame behind the data streamed through the 24-bit RGB parallel interface. In structured light mode, the 48 bit-planes can be pre-loaded from Flash memory and then sequenced with a combination of patterns with different bit depths. To synchronize a camera to the displayed patterns, the DLPC350 supports three trigger modes: mode 0, mode 1, and mode 2. In mode 0, the vertical sync is used as trigger input. In mode 1, a TRIG_IN_1 pulse indicates to the DLPC350 to advance to the next pattern, while TRIG_IN_2 starts and stops the pattern sequence. In both modes 0 and 1, TRIG_OUT_1 frames the exposure time of the pattern, while TRIG_OUT_2 indicates the start of the pattern sequence or internal buffer boundary of 24-bit planes. In mode 2, the TRIG_IN_1 signal toggles between two consecutive patterns, while a TRIG_IN_2 pulse advances to the next pair of patterns. In trigger mode 0, shown in Figure 5, the VSYNC starts the pattern sequence display. The pattern sequence consists of a series of three consecutive patterns. The first pattern sequence consists of P1, P2, and P3. Since P3 is an RGB pattern, it is shown with its time sequential representation of P3.1, P3.2, and P3.3. The second pattern sequence consists of three patterns: P4, P5, and P6. The third sequence consists of P7, P8, and P9. TRIG_OUT_1 frames each pattern exposed, while TRIG_OUT_2 indicates the start of each of the three pattern sequences. An example of trigger mode 1 is shown in Figure 6. Pattern sequences of four are displayed. TRIG_OUT_1 frames each pattern exposed, while TRIG_OUT_2 indicates the start of each four-pattern sequence. TRIG_IN_1 pulses advance the pattern. Another example for mode 1 is shown in Figure 7, where pattern sequences of three are displayed. TRIG_OUT_1 frames each pattern displayed, while TRIG_OUT_2 indicates the start of each three-pattern sequence. TRIG_IN_2 serves as a start/stop signal. When high, the pattern sequence starts or continues. Note that in the middle of displaying the P4 pattern, TRIG_IN_2 is low, so the sequence stops displaying P4. When TRIG_IN_2 is raised, the pattern sequence continues where it stopped by re-displaying P4. For trigger mode 2, shown in Figure 8, TRIG-IN_1 alternates between two patterns, while TRIG_IN_2 advances to the next pair of patterns. Table 1 shows the allowed pattern combinations in relation to the bit depth of the pattern. 6 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: DLPC350 DLPC350 www.ti.com DLPS029A – APRIL 2013 – REVISED MAY 2013 Figure 5.

In this configuration, the DLPC350 controller supports a 24-bit parallel RGB input, typical of LCD interfaces, from an external source or processor. This system supports both still and motion video sources. However, the controller only supports sources with periodic synchronization pulses. This is ideal for motion video sources, but can also be used for still images by maintaining periodic syncs and only sending a new frame of data when needed. The still image must be fully contained within a single video frame and meet the frame timing constraints. The DLPC350 refreshes the displayed image at the source frame rate and repeats the last active frame for intervals in which no new frame has been received. Figure 9.

Table 2. Functional Pin Descriptions (1) PIN NAME NO. I/O POWER I/O TYPE INTERNAL TERMINATION CLK SYSTEM DESCRIPTION Async Power Good is an active high signal with hysteresis that is generated by an external power supply or voltage monitor. A high value indicates all power is within operating voltage specs and the system is safe to exit its reset state. A transition from high to low should indicate that the controller or DMD supply voltage will drop below their rated minimum level within the next 0.5ms (POSENSE must remain active high during this interval). This is an early warning of an imminent power loss condition. This warning is required to enhance long term DMD reliability. A DMD park sequence, followed by a full controller reset, is performed by the DLPC350 when PWRGOOD goes low for a minimum of 4us protecting the DMD. This minimum de-assertion time is used to protect the input from glitches. Following this the DLPC350 will be held in its reset state as long as PWRGOOD is low. PWRGOOD must be driven high for normal operation. The DLPC350 will acknowledge PWRGOOD as active once it’s been driven high for a minimum of 625ns. Utilizes hysteresis. Async Power-On Sense is an active high input signal with hysteresis that is generated by an external voltage monitor circuit. POSENSE must be driven inactive (low) when any of the controller supply voltages are below minimum operating voltage specs. POSENSE must be active (high) when all controller supply voltages remain above minimum specs. CONTROL PWRGOOD POSENSE H19 VDDC I4 H I4 H G21 POWER_ON_OFF N21 VDD33 B2 Async Power On/Off is an active high signal that indicates the power of the system. Power On/Off is high when the system is in powerup state, and low when the system is in standby. Power On/Off can also be used to power on/off an external power supply.

The result of this test (pass/fail) is recorded in the system status. If memory test fails, the initialization process is halted. INIT_DONE is asserted twice to indicate an error situation. See Figure 25 and note that GPIO26 is the INIT_DONE signal. Async This signal is sampled during power-up. If the signal is low, the I2C addresses are 0x34 and 0x35. If the signal is low, the I2C are 0x3A and 0x3B. Once the system has been initialized, this signal is available as a GPIO.

(2) (3) (4) 12 Port 1 can be used to support multiple source options for a given product (that is. HDMI, BT656). To do so, the data bus from both source components must be connected to the same port 1 pins and control given to the DLPC350 to tri-state the "inactive" source. Tying them together like this will cause some signal degradation due to reflections on the tri-stated path. The A, B, and C input data channels of Port 1 can be internally swapped for optimum board layout. Sources feeding less than the full 10-bits per color component channel should be MSB justified when connected to the DLPC350 and LSBs tied off to zero. For example, an 8-bit per color input should be connected to bits 9:2 of the corresponding A, B, or C input channel. BT656 are 8 or 10 bits in width. If a BT656 type input is utilized, the data bits must be MSB justified as with the other types of input sources on either of the A, B, or C data input channels.

Some GPIOs have one or more "alternative use" modes which are also software configurable. The reset default for all optional GPIOs is as an input signal. However, any alternate function connected to these GPIO pins with the exception of General Purpose Clocks and PWM Generation, will be reset. An external pull-up to the 3.3V supply is required for each signal configured as open-drain. External pull-up or pull-down resistors may be required to ensure stable operation before software is able to configure these ports.

Normal mode refers to operation during full functionality, active product operation. Typical values correspond to power dissipated on nominal process devices operating at nominal voltage and 70°C junction temperature (approximately 25°C ambient) displaying typical video-graphics content from a high frequency source. Maximum values correspond to power dissipated on fast process devices operating at high voltage and 105°C junction temperature (approximately 55°C ambient) displaying typical video-graphics content from a high frequency source. The increased power dissipation observed on fast process devices operated at maximum recommended temperatures is primarily a result of increased leakage current.

The performance may be further limited by interface voltage and PCB routing. Note that these vales do not include any tolerance variation of the external crystal/oscillator, nor do they include any associated jitter. LPDDR Slew rate for the rising edge is measured between VILD(DC) to VIHD(AC) where VILD(DC) = 0.3*VDDQ and VILD(AC) = 0.8*VDDQ. LPDDR Slew rate for the rising edge is measured between VILD(DC) to VIHD(AC) where VILD(DC) = 0.7*VDDQ and VILD(AC) = 0.2*VDDQ. The DMD setup and hold time window must be de-rated by 300 ps for each 0.1 V/ns reduction in slew rate below 1V/ns. Thus a 0.7 V/ns slew rate increases this window by 900 ps from 1400 ps to 2300 ps. Output setup and hold values already include clock jitter, DCD, SSO, ISI noise and PCB variation. Only routing skew and DMD setup/hold need to be considered in system timing analysis.

Default Conditions At system power-up, the DLPC350 performs a power-up initialization routine that will default the controller to its normal power mode, related clocks will be enabled at their full rate, and associated resets will be released. Most other clocks will default to "disabled" with associated resets asserted until released by the processor. These same defaults will also be applied as part of all system reset events that occur without removing or recycling power. Following power-up or system reset initialization, the system will boot from an external flash memory after which it will enable the rest of the controller clocks. Once system initialization is complete, application software will determine if and when to enter standby mode. 1.2V System Power The controller supports a low cost power delivery system with a single 1.2V power source derived from a switching regulator. The main core should receive 1.2V power directly from the regulator output, and the internal DLPC350 PLLs (VDD_12_PLLM, VDD_12_PLLD) should receive individually filtered versions of this 1.2V power. See PLL for specific filter recommendations. 1.8V System Power A single 1.8V power source should be used to supply both internal PLLs (VDD_18_PLLM, VDD_18_PLLD). In order to keep the power as clean as possible, it is recommended that this power be sourced via a linear regulator that is individually filtered for each PLL. See PLL for specific filter recommendations. 1.9V System Power In order to maximize signal integrity, it is recommended that an independent linear regulator be used to source the 1.9V supply that supports the DMD interface (VDD_DMD). To achieve maximum performance, this supply must be tightly regulated to operating within a 1.9V ±0.1V range. 3.3V System Power The DLPC350 supports a low cost power delivery system with a single 3.3V power source derived from a switching regulator. This 3.3V power will supply all LVCMOS I/O. 3.3V power (VDD33) should remain active in all power modes for which the 1.2V core power is applied. FPD-Link Input LVDS System Power The controller supports an FPD-Link compatible LVDS input for an additional method of inputting video/graphics data for display. This interface has some special controller power considerations that are separate from the other controller 1.2V or 3.3V power rails. An FPD-Link 1.2V power pin configuration example is shown in below. Figure 22. FPD-Link 1.2V Power Pin Configuration 38 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: DLPC350 DLPC350 www.ti.com DLPS029A – APRIL 2013 – REVISED MAY 2013 In addition, it is recommended to place the 0.1µF low ESR (equivalent series resistance capacitors to ground as close to the FPD-Link power pins of the DLPC350 as possible. FPD-Link 3.3V power pins should also use external capacitors in the same manner as the 1.2V pins. When FPD-Link is not utilized, the filtering can be omitted. The corresponding voltages, however, MUST still be provided in order to avoid potential long-term reliability issues. Figure 23. Initialization Timeline System Power-Up/Down Sequence Although the DLPC350 requires an array of power supply voltages, (e.g., VDDC, VDD_1X_PLLX, VCC_18, VCC_DMD, VCCXX_FPD), there are no restrictions regarding the relative order of power supply sequencing to avoid damaging the DLPC350. This is true for both power-up and power-down. Similarly, there is no minimum time between powering up or powering down the different supplies of the DLPC350. Note, however, that it is not uncommon for there to be power-sequencing requirements for other devices that share power supplies with the DLPC350. Although there is no risk of damaging the DLPC350 as a result of a given power sequence, from a functional standpoint there are a few specific power-sequencing recommendations to ensure proper operation. • • 1.2V Core power should be applied whenever any I/O power is applied. This ensures that the powered I/O pins are set to a known state. Thus, it is recommended that core power be applied first. Other supplies should be applied only after the 1.2V DLPC350 core has ramped up. All controller power should be applied before POSENSE is asserted to ensure proper power-up initialization is performed. 1.8V PLL power, 1.9V I/O power and 3.3V I/O power should remain applied as long as 1.2V core power is applied and POSENSE is asserted. It is assumed that all DLPC350 power-up sequencing is handled by external hardware. It is also assumed that an external power monitor will hold the DLPC350 in system reset during power-up (itaht is, POSENSE = 0). It should continue to assert system reset until ALL DLPC350 voltages have reached minimum specified voltage levels. During this time, all controller I/O will either be tri-stated or driven low. The master PLL (PLLM) will be released from reset upon the low to high transition of POSENSE but the DLPC350 will keep the rest of the controller in reset for an additional 100 ms to allow the PLL to lock and stabilize its outputs. After this 100 ms delay, internal resets will be de-asserted causing the microprocessor to begin its boot-up routine.

Power-Up/Down Timing Power-On Sense (POSENSE) Support It is difficult to set up a power monitor to trip exactly on the DLPC350 minimum supply voltages specifications. Thus, it is recommended that the external power monitor generating POSENSE target its threshold to 90% of the minimum supply voltages and ensure that POSENSE remain low for a sufficient amount of time to allow all supply voltages to reach minimum controller requirements and stabilize. Note that the trip voltage for detecting the loss of power is not critical for POSENSE and thus may be as low as 50% of rated supply voltages. In addition, the reaction time to respond to a low voltage condition is not critical for POSENSE. INIT_DONE has much more critical requirements in these areas. Power-Good (PWRGOOD) Support The PWRGOOD signal is defined to be an early warning signal that should alert the controller 500 µs before DC supply voltages have dropped below specifications. This allows the controller time to park the DMD, ensuring the integrity of future operation. It is recommended that monitor sensing PWRGOOD be on the input side of the supply regulators. 5V Tolerant Support With the exception of USB_DAT, the DLPC350 does not support any other 5V tolerant I/O. 40 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: DLPC350 DLPC350 www.ti.com DLPS029A – APRIL 2013 – REVISED MAY 2013 Power Reset Operation Immediately following a power-up event, the DLPC350 hardware will automatically bring up the Master PLL and place the controller in NORMAL power mode. It will then follow the standard System Reset procedure (see next section). System Reset Operation Immediately following any type of system reset (power-up reset, PWRGOOD reset, etc.), the DLPC350 will automatically return to NORMAL power mode and return to the following state: • • • • • • • • All GPIO will tri-state and as a result all GPIO controlled voltage switches will default to enabling power to all the DLPC350 supply lines (assuming that these outputs are externally pulled-high). The Master PLL will remain active (it is only reset on a power-up reset) and most of the derived clocks will be active. However, only those resets associated with the internal processor and its peripherals will be released. The internal processor associated clocks will default to their full clock rates, as boot-up occurs at full speed). The PLL feeding the DDR DMD Interface (PLLD) will default to its Power Down mode, and all derived clocks will be inactive with the corresponding resets asserted. The DMD interface (except DMD_DRC_OE) will default its outputs to a logic low state. DMD_DRC_OE will default to tri-state, but should be pulled high via an external 30KΩ to 51KΩ pull-up resistor on the PCB. All resets outputted by the DLPC350 will remain asserted until released by the internal processor (after bootup). The DLPC350 will boot-up from external Flash. After the DLPC350 boots, it will: – Configure the programmable DDR Clock Generator (DCG) clock rates (i.e. the DMD LPDDR interface rate). – Enable the DCG PLL (PLLD) while holding the divider logic in reset. – Once the DCG PLL locks, the firmware will set the DMD clock rates. – The DLPC350 firmware will then release the DCG divider logic resets, which in turn, will enable all derived DCG clocks. After the clocks are configured, an Internal Memory Test is performed. See Figure 25 and note that GPIO26 is the INIT_DONE signal. Application software should wait for a wake-up command from the user. Once the controller is requested to "wake-up," the software should place the controller back in NORMAL mode and re-initialize clocks and resets as required. Figure 25.

For inputs with internal pull-up or pull-down resistors, it is unnecessary to add an external pull-up or pull-down unless specifically recommended. Note that internal pull-up and pull-down resistors are weak and should not be expected to drive the external line. Bi-directional pins are configured as inputs as a reset default. Unless specifically specified, pull-up and pull-down resistors can be 10 kΩ. Unused output-only pins can be left open. Program Memory Flash Interface The DLPC350 provides three external program memory chip selects. • PM_CS_0 - available for optional Flash device ( ≤ 128 Mb) • PM_CS_1 - mandatory CS for Boot Flash device (Standard "NOR" Flash ≤ 128 Mb) • PM_CS_2 - available for optional Flash device ( ≤ 128 Mb) The Flash access timing is software programmable up to 31 wait states. Wait state resolution is 6.7 nanoseconds in normal mode, and 53.57 nanoseconds in low power modes. To calculate the wait state values: Wait State Value = Device Access Time ÷ Wait State Resolution where the Wait State Value is rounded up. This equation assume a maximum single direction trace length of 75 mm. When another device such as an additional Flash is used in conjunction with the Boot Flash, stub lengths must be kept short and located as close as possible to the Flash end of the route. The DLPC350 provides enough Program Memory address pins to support a flash device up to 128 Mb. There are two bi-directional pins (PM_ADDR_22 and PM_ADDR_21) that can be programmed as additional address pins once the software configures them. Enabling PM_ADDR_21 increases the Flash size from 32 Mb to 64 Mb. Enabling PM_ADDR_22 as well as PM_ADDR_21 increases the Flash size to 128 Mb. If these pins are used, then they require board-level pull-down resistors to prevent the Flash address bits from floating. Thermal Considerations The underlying thermal limitation for the DLPC350 is that the maximum operating junction temperature (TJ) must not be exceeded (see Recommended Operating Conditions). This temperature is dependent on operating ambient temperature, airflow, PCB design (including the component layout density and the amount of copper used), power dissipation of the DLPC350, and power dissipation of surrounding components. The DLPC350 package is designed primarily to extract heat through the power and ground planes of the PCB, thus copper content and airflow over the PCB are important factors. Table 17.

This should be used for heat sink analysis only. Thermal coefficients abide by JEDEC Standard 51. RθJA is the thermal resistance of the package as measured using a JEDEC defined standard test PCB. This JEDEC test PCB is not necessarily representative of the DLPC350 PCB and thus the reported thermal resistance may not be accurate in the actual product application. Although the actual thermal resistance may be different , it is the best information available during the design phase to estimate thermal performance. Example: (3 W) x (0.33 °C/W) = approximately a 1.00°C temperature rise.

This reference may be supplied via a crystal or oscillator. The DLPC350 accepts a reference clock of 32 MHz with a maximum frequency variation of 100 ppm (including aging, temperature and trim component variation). When a crystal is used, several discrete components are also required as shown in Figure 26. Figure 26. Recommended Crystal Oscillator Configuration Table 18.

The benefit of an oscillator is that it can be made to provide a spread-spectrum clock that reduces EMI. Note, however, that the DLPC350 can only accept 0%, ±0.5%, and ±1.0% (center-spread modulation), and a triangular waveform. Similar to the crystal option, the oscillator input frequency is limited to 32 MHz. It is assumed that the external crystal or oscillator stabilizes within 50 ms after stable power is applied. PLL The following guidelines are recommended to achieve desired controller performance relative to the internal PLLs. The DLPC350 contains two PLLs (PLLM and PLLD), each of which have dedicated 1.2V digital and 1.8V analog supply. These 1.2V PLL pins should be individually isolated from the main 1.2V system supply via a ferrite bead. The impedance of the ferrite bead should be much greater than the capacitor at frequencies where noise is expected. The impedance of the ferrite bead must also be less than 0.5Ω in the frequency range of 100-300KHz and greater than 10Ω at frequencies greater than 100MHz. As a minimum, the 1.8V analog PLL power and ground pins should be isolated using an LC filter with a ferrite bead serving as the inductor and a 0.1µF capacitor on the DLPC350 side of the ferrite bead. It is recommended that this 1.8V PLL power be supplied from a dedicated linear regulator and each PLL should be individually isolated from the regulator. The same ferried recommendations described for the 1.8V analog PLL supply apply to the 1.2V digital PLL supply. When describing the overall supply filter network, care must be taken to ensure that no resonances occur. Particular care must be taken in the 1-2MHz band, as this coincides with the PLL natural loop frequency.

PLL Filter Layout High frequency decoupling is required for both 1.2V and 1.8V PLL supplies and should be provided as close as possible to each of the PLL supply package pins. It is recommended that decoupling capacitors be placed under the package on the opposite side of the board. High quality, low-ESR, monolithic, surface mount capacitors should be used. Typically 0.1 µF for each PLL supply should be sufficient. The length of a connecting trace increases the parasitic inductance of the mounting and thus, where possible, there should be no trace, allowing the via to butt up against the land itself. Additionally the connecting trance should be made as wide as possible. Further improvement can be made by placing vias to the side of the capacitor lands or doubling the number of vias. The location of bulk decoupling depends on the system design. Typically a good ceramic capacitor in the 10 µF range is adequate. 46 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: DLPC350 DLPC350 www.ti.com DLPS029A – APRIL 2013 – REVISED MAY 2013 Board Level Test Support The In-Circuit Tri-State Enable signal (ICTSEN) is a board level test control signal.
