Introduction
The TVP5147 device is a high-quality, single-chip digital video decoder that digitizes and decodes all popular
baseband analog video formats into digital component video. The TVP5147 decoder supports the
analog-to-digital (A/D) conversion of component YPbPr signals, as well as the A/D conversion and decoding
of NTSC, PAL, and SECAM composite and S-video into component YCbCr. This decoder includes two 10-bit
30-MSPS A/D converters (ADCs). Preceding each ADC in the device, the corresponding analog channel
contains an analog circuit that clamps the input to a reference voltage and applies a programmable gain and
offset. A total of 10 video input terminals can be configured to a combination of YPbPr, CVBS, or S-video video
inputs.
Composite or S-video signals are sampled at 2× the square-pixel or ITU-R BT.601 clock frequency, line-locked
alignment, and are then decimated to the 1× 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 and S-video 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, as well as a patented chroma transient improvement (CTI)
circuit.
The following output formats can be selected: 20-bit 4:2:2 YCbCr or 10-bit 4:2:2 YCbCr.
The TVP5147 decoder generates synchronization, blanking, field, active video window, horizontal and vertical
syncs, clock, genlock (for downstream video encoder synchronization), host CPU interrupt and programmable
logic I/O signals, in addition to digital video outputs.
The TVP5147 decoder includes methods for advanced vertical blanking interval (VBI) data retrieval. The VBI
data processor (VDP) slices, parses, and performs error checking on teletext, closed caption (CC), and other
VBI data. A built-in FIFO stores up to 11 lines of teletext data, and with proper host port synchronization,
full-screen teletext retrieval is possible. The TVP5147 decoder can pass through the output formatter 2×
sampled raw luma data for host-based VBI processing.
The main blocks of the TVP5147 decoder include:
• Robust sync detection for weak and noisy signals as well as VCR trick modes
• Y/C separation by 2-D 5-line adaptive comb or chroma trap filter
• Two 10-bit, 30-MSPS A/D converters with analog preprocessors [clamp and automatic gain control
(AGC)]
• Analog video output
• Luminance processor
• Chrominance processor
• Clock/timing processor and power-down control
• Software-controlled power-saving standby mode
• Output formatter
• I2C host port interface
• VBI data processor
• Macrovision copy protection detection circuit (Type 1, 2, 3, and separate color stripe detection)
• 3.3-V tolerant digital I/O ports

2.1.1 Video Input Switch Control
The TVP5147 decoder has two analog channels that accept up to 10 video inputs. The user can configure
the internal analog video switches via the I2C interface. The 10 analog video inputs can be used for different
input configurations, some of which are:

•
Up to 10 selectable individual composite video inputs
Up to four selectable S-video inputs
Up to three selectable analog YPbPr video inputs and one CVBS input
Up to two selectable analog YPbPr video inputs, two S-video inputs, and two CVBS inputs
The input selection is performed by the input select register at I2C subaddress 00h (see Section 2.11.1).
2.1.2 Analog Input Clamping
An internal clamping circuit restores the ac-coupled video signal to a fixed dc level. The clamping circuit
provides line-by-line restoration of the video sync level to a fixed dc reference voltage. The selection between
bottom and mid clamp is performed automatically by the TVP5147 decoder.
2.1.3 Automatic Gain Control
The TVP5147 decoder uses two programmable gain amplifiers (PGAs), one per channel. The PGA can scale
a signal with a voltage-input compliance of 0.5-VPP to 2.0-VPP to a full-scale 10-bit A/D output code range.
A 4-bit code sets the coarse gain with individual adjustment per channel. Minimum gain corresponds to a code
0x0 (2.0-VPP full-scale input, −6-dB gain) while maximum gain corresponds to code 0xF (0.5 VPP full scale,
+6-dB gain). The TVP5147 decoder also has 12-bit fine gain controls for each channel and applies
independently to coarse gain controls. For composite video, the input video signal amplitude can vary
significantly from the nominal level of 1 VPP. The TVP5147 decoder can adjust its PGA setting automatically:
an automatic gain control (AGC) can be enabled and can adjust the signal amplitude such that the maximum
range of the ADC is reached without clipping. Some nonstandard video signals contain peak white levels that
saturate the ADC. In these cases, the AGC automatically cuts back gain to avoid clipping. If the AGC is on,
then the TVP5147 decoder can read the gain currently being used.
The TVP5147 AGC comprises the front-end AGC before Y/C separation and the back-end AGC after Y/C
separation. The back-end AGC restores the optimum system gain whenever an amplitude reference such as
the composite peak (which is only relevant before Y/C separation) forces the front-end AGC to set the gain
too low. The front-end and back-end 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 front-end and back-end AGC algorithms can be
independently controlled using the AGC white peak processing register located at subaddress 74h. The
TVP5147 gain increment speed and gain increment delay can be controlled using the AGC increment speed
register located at subaddress 78h and the AGC increment delay register located at subaddress 79h.
2.1.4 Analog Video Output
One of the analog input signals is available at the analog video output terminal, which is shared with input
selected by I2C registers. The signal at this terminal must be buffered by a source follower. The nominal output
voltage is 2 V p-p, thus the signal can be used to drive a 75-Ω line. The magnitude is maintained with an AGC
in 16 steps controlled by the TVP5147 decoder. In order to use this function, terminal VI_1_A must be set as
an output terminal. The input mode selection register also selects an active analog output signal.
2.1.5 A/D Converters
All ADCs have a resolution of 10 bits and can operate up to 30 MSPS. All A/D channels receive an identical
clock from the on-chip phase-locked loop (PLL) at a frequency between 24 MHz and 30 MHz. All ADC
reference voltages are generated internally.

2.2 Digital Video Processing
Figure 2−2 is a block diagram of the TVP5147 digital video decoder processing. This block receives digitized
video signals from the ADCs and performs composite processing for CVBS and S-video inputs and YCbCr
signal enhancements for CVBS and S-video inputs. It also generates horizontal and vertical syncs and other
output control signals such as genlock for CVBS and S-video inputs. Additionally, it can provide field
identification, horizontal and vertical lock, vertical blanking, and active video window indication signals. The
digital data output can be programmed to two formats: 20-bit 4:2:2 with external syncs or 10-bit 4:2:2 with
embedded/separate syncs. The circuit detects pseudosync pulses, AGC pulses, and color striping in
Macrovision-encoded copy-protected material. Information present in the VBI interval can be retrieved and
either inserted in the ITU-R BT.656 output as ancillary data or stored in internal FIFO and/or registers for
retrieval via the host port interface.

2.2.1 2× Decimation Filter
All input signals are typically oversampled by a factor of 2 (27 MHz). The A/D outputs initially pass through
decimation filters that reduce the data rate to 1× the pixel rate. The decimation filter is a half-band filter.
Oversampling and decimation filtering can effectively increase the overall signal-to-noise ratio by 3 dB.
2.2.2 Composite Processor
Figure 2−3 is a block diagram of the TVP5147 digital composite video processing circuit. This processing
circuit receives a digitized composite or S-video signal from the ADCs and performs Y/C separation (bypassed
for S-video input), chroma demodulation for PAL/NTSC and SECAM, and YUV signal enhancements.
SLES099C—March 2007
TVP5147PFP

Functional Description
The 10-bit composite video is multiplied by the subcarrier signals in the quadrature demodulator to generate
color difference signals U and V. 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 remodulated 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 host port.

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 2−4 through Figure 2−7 represent the frequency responses of the wideband color
low-pass filters.

2.2.2.2
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 2−8 through Figure 2−11. TI’s 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.

2.2.3 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 2−12 illustrates the basic functions
of the luminance data path. In the case of S-video, the luminance signal bypasses the comb filter or chroma

components of the luminance signal. Figure 2−13, Figure 2−14, and Figure 2−15 show the characteristics of
the peaking filter at four different gain settings that are user-programmable via the I2C interface.

Color Transient Improvement
Color transient improvement (CTI) enhances horizontal color transients. The color difference signal transition
points are maintained, but the edges are enhanced for signals which have bandwidth-limited color
components.
2.3 Clock Circuits
An internal line-locked PLL generates the system and pixel clocks. A 14.318-MHz clock is required to drive
the PLL. This can be input to the TVP5147 decoder at the 1.8-V level on terminal 74 (XTAL1), or a crystal of
14.318-MHz fundamental resonant frequency can be connected across terminals 74 and 75 (XTAL2). If a
parallel resonant circuit is used as shown in Figure 2−16, then the external capacitors must have the following
relationship:
CL1 = CL2 = 2CL − CSTRAY,
where CSTRAY is the terminal capacitance with respect to ground. Figure 2−16 shows the reference clock
configurations. The TVP5147 decoder generates the DATACLK signal used for clocking data.

2.4 Real-Time Control (RTC)
Although the TVP5147 decoder is a line-locked system, the color burst information is used to determine
accurately the color subcarrier frequency and phase. This ensures proper operation with nonstandard video
signals that do not follow exactly the required frequency multiple between color subcarrier frequency and video
line frequency. The frequency control word of the internal color subcarrier PLL and the subcarrier reset bit are
transmitted via terminal 37 (GLCO) for optional use in an end system (for example, by a video encoder). The
frequency control word is a 23-bit binary number. The instantaneous frequency of the color subcarrier can be
calculated using the following equation:
F PLL +
F ctrl
2 23
F sclk
where FPLL is the frequency of the subcarrier PLL, Fctrl is the 23-bit PLL frequency control word, and Fsclk is
two times the pixel frequency. This information can be generated on the GLCO terminal. Figure 2−17 shows
the detailed timing diagram.

2.5.2 Embedded Syncs
Standards with embedded syncs insert the SAV and EAV codes into the data stream on the rising and falling
edges of AVID. These codes contain the V and F bits which also define vertical timing. Table 2−3 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.
The P bits are protection bits:
P3 = V xor H; P2 = F xor H; P1 = F xor V; P0 = F xor V xor H

2.6 I2C Host Interface
Communication with the TVP5147 decoder is via an I2C host interface. The I2C standard consists of two
signals, the serial input/output data (SDA) line and the serial input clock line (SCL), which carry information
between the devices connected to the bus. A third signal (I2CA) is used for slave address selection. Although
an I2C system can be multimastered, the TVP5147 decoder functions as a slave device only.
SLES099C—March 2007
TVP5147PFP
23
Functional Description
Because SDA and SCL are kept open-drain at a logic-high output level or when the bus is not driven, the user
must connect SDA and SCL to a positive supply voltage via a pullup resistor on the board. The slave addresses
select signal, terminal 37 (I2CA), enables the use of two TVP5147 devices tied to the same I2C bus, because
it controls the least significant bit of the I2C device address.

2.6.1 Reset and I 2C Bus Address Selection
The TVP5147 decoder can respond to two possible chip addresses. The address selection is made at reset
by an externally supplied level on the I2CA terminal. The TVP5147 decoder samples the level of terminal 37
at power up or at the trailing edge of RESETB and configures the I2C bus address bit A0. The I2CA terminal
has an internal pulldown resistor to pull the terminal low to set a zero.

2.7 VBI Data Processor
The TVP5147 VBI data processor (VDP) slices various data services like teletext (WST, NABTS), closed
caption (CC), wide screen signaling (WSS), program delivery control (PDC), vertical interval time code (VITC),
video program system (VPS), copy generation management system (CGMS) data, and electronic program
guide (Gemstar) 1x/2x. Table 2−6 shows the supported VBI system.
These services are acquired by programming the VDP to enable the reception of one or more vertical blank
interval (VBI) data standard(s) during the VBI. The VDP can be programmed on a line-per-line basis to enable
simultaneous reception of different VBI formats, one per line. The results are stored in a FIFO and/or registers.
Because of the high data bandwidth, teletext results are stored in FIFO only. The TVP5147 decoder provides
fully decoded V-Chip data to the dedicated registers at subaddresses 80 0540h−80 0543h.

2.7.1 VBI FIFO and Ancillary Data in Video Stream
Sliced VBI data can be output as ancillary data in the video stream in ITU-R BT.656 mode. VBI data is output
on the Y[9:2] terminals during the horizontal blanking period. Table 2−7 shows the header format and
sequence of the ancillary data inserted into the video stream. This format is also used to store any VBI data
into the FIFO. The size of the FIFO is 512 bytes. Therefore, the FIFO can store up to 11 lines of teletext data
with the NTSC NABTS standard.

Functional Description
2.7.2 VBI Raw Data Output
The TVP5147 decoder can output raw A/D video data at twice the sampling rate for external VBI slicing. This
is transmitted as an ancillary data block, although somewhat differently from the way the sliced VBI data is
transmitted in the FIFO format as described in Section 2.7.1. The samples are transmitted during the active
portion of the line. VBI raw data uses ITU-R BT.656 format having only luma data. The chroma samples are
replaced by luma samples. The TVP5147 decoder inserts a four-byte preamble 000h 3FFh 3FFh 180h before
data start. There are no checksum bytes and fill bytes in this mode.

2.8 Reset and Initialization
Reset is initiated at power up or any time terminal 34 (RESETB) is brought low. Table 2−9 describes the status
of the TVP5147 terminals during and immediately after reset.

Figure 2−24. Reset Timing
The TVP5147 requires that pin 69 (C_1/GPIO) be held LOW. If using the 20-/16-bit mode or using this pin as
GPIO, then this pin must be pulled low through a 2.2-kΩ pulldown resistor (see Figure 5−1). If unused, this
pin can be shorted to ground. (Note: If using the 20-/16-bit mode and only using the 16 MSBs, it is possible
to short pin 69 to GND, but the current for IOVDD will increase by 2 or 3 mA.)

Afterward, the user programs the device as usual.
2.9 Adjusting External Syncs
The proper sequence to program the following external syncs is:
•
•
•
To set NTSC, PAL-M, NTSC 443, PAL60 (525-line modes):
−
Set the video standard to NTSC (register 02h)
−
Set HSYNC, VSYNC, VBLK, and AVID external syncs (registers 16h through 24h)
To set PAL, PAL-N, SECAM (625-line modes):
−
Set the video standard to PAL (register 02h)
−
Set HSYNC, VSYNC, VBLK, and AVID external syncs (registers 16h through 24h)
For autoswitch, set the video standard to autoswitch (register 02h)
2.10 Internal Control Registers
The TVP5147 decoder is initialized and controlled by a set of internal registers that define the operating
parameters of the entire device. Communication between the external controller and the TVP5147 is through
a standard I2C host port interface, as described earlier. Table 2−10 shows the summary of these registers.
Detailed programming information for each register is described in the following sections. Additional registers
are accessible through an indirect procedure involving access to an internal 24-bit address wide VBUS.
Table 2−11 shows the summary of the VBUS registers.
NOTE: Do not write to reserved registers. Reserved bits in any defined register must be written
with 0s, unless otherwise noted.

During the duration of the vertical blanking as defined by the VBLK start and stop line registers at
subaddresses 22h through 25h (see Sections 2.11.22 and 2.11.23), the chroma samples are replaced by luma
samples. This feature can be used to support VBI processing performed by an external device during the
vertical blanking interval. In order to use this bit, the output format must be 10-bit ITU-R BT.656 mode.

NOTE: If all 4 bits of the lower nibble are set to logic 1 (that is, no amplitude reference selected),
then the front-end analog and digital gains are automatically set to nominal values of 2 and
2304, respectively.
If all 4 bits of the upper nibble are set to logic 1 (that is, no amplitude reference selected), then
the back-end gain is set automatically to unity.
If the input sync height is greater than 100% and the AGC-adjusted output video amplitude becomes less than
100%, then the back-end scale factor attempts to increase the contrast in the back end to restore the video
amplitude to 100%.

Functional Description
For an NABTS system, the packet prefix consists of five bytes. Each byte contains 4 data bits (D[3:0])
interlaced with 4 Hamming protection bits (H[3:0]):

Only data portion D[3:0] from each byte is applied to a teletext filter function with corresponding pattern bits
P[3:0] and mask bits M[3:0]. The filter ignores the Hamming protection bits.
For WST system (PAL or NTSC), the packet prefix consists of two bytes. The two bytes contain three bits of
magazine number (M[2:0]) and five bits of row address (R[4:0]), interlaced with eight Hamming protection bits
H[7:0]:

The mask bits enable filtering using the corresponding bit in the pattern register. For example, a 1 in the LSB
of mask 1 means that the filter module must compare the LSB of nibble 1 in the pattern register to the first data
bit on the transaction. If these match, then a true result is returned. A 0 in a bit of mask means that the filter
module must ignore that data bit of the transaction. If all 0s are programmed in the mask bits, then the filter
matches all patterns returning a true result (default 00h).

The FIFO full error flag is set when the current line of VBI data cannot enter the FIFO. For example, if the FIFO
has only 10 bytes left and teletext is the current VBI line, then the FIFO full error flag is set, but no data is written
because the entire teletext line does not fit. However, if the next VBI line is closed caption requiring only 2 bytes
of data plus the header, then this goes into the FIFO even if the full error flag is set.

The interrupt status 0 and 1 registers represent the interrupt status after applying mask bits. Therefore, the
status bits are the result of a logical AND between the raw status and mask bits. The external interrupt terminal
is derived from this register as an OR function of all nonmasked interrupts in this register.
Reading data from the corresponding register does not clear the status flags automatically. These flags are
reset using the corresponding bits in interrupt clear 0 and 1 registers.

Designing With PowerPADt Devices
The TVP5147 device is housed in a high-performance, thermally enhanced, 80-terminal PowerPAD package
(TI package designator: 80PFP). 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 80-terminal PFP PowerPAD package is 8 mm × 8 mm.
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
PowerPADt Thermally Enhanced Package Application Report, (SLMA002), available via the TI Web pages
beginning at URL: http://www.ti.com
For the TVP5147 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 must 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).

http://www.ti.com/productcontent for the latest availability information and additional product content details.
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)
