SLES206 – MAY 2007
DESCRIPTION
TVP7002 is a complete solution for digitizing video and graphic signals in RGB or YPbPr color spaces. The
device supports pixel rates up to 165 MHz. Therefore, it can be used for PC graphics digitizing up to the VESA
standard of UXGA (1600 × 1200) resolution at 60-Hz screen refresh rate, and in video environments for the
digitizing of digital TV formats, including HDTV up to 1080p.
The TVP7002 is powered from 3.3-V and 1.9-V supply and integrates a triple high-performance analog-to-digital
(A/D) converter with clamping functions and variable gain, independently programmable for each channel. The
clamp timing window is provided by an external pulse or can be generated internally. The TVP7002 includes
analog slicing circuitry on the SOG inputs to support sync-on-luminance or sync-on-green extraction. In addition,
TVP7002 can extract discrete HSYNC and VSYNC from composite sync using a sync slicer.
TVP7002 also contains a complete horizontal PLL block to generate a pixel clock from the HSYNC input. Pixel
clock output frequencies range from 12 MHz to 165 MHz.
All programming of the part is done via an industry-standard I2C interface, which supports both reading and
writing of register settings. The TVP7002 is available in a space-saving 100-pin TQFP PowerPAD package.

SLES206 – MAY 2007
FUNCTIONAL DESCRIPTION
Analog Channel
The TVP7002 contains three identical analog channels that are independently programmable. Each channel
consists of a clamping circuit, programmable gain control, programmable offset control, and an ADC.
Analog Input Switch Control
TVP7002 has three analog channels that accept up to ten video inputs. The user can configure the internal
analog video switches via the I2C interface. The ten analog video inputs can be used for different input
configurations, some of which are:
• Up to three SDTV, EDTV, or HDTV component video inputs (limited by number of SOG inputs)
• Up to two 5-wire PC graphics inputs (limited by number of HSYNC and VSYNC inputs)
The input selection is performed by the input select register at I2C subaddress 19h a 1Ah (see Input Mux Select
1 and Input Mux Select 2).
Video Formats Supported
The TVP7002 supports A/D conversion of SDTV (480i, 576i), EDTV (480p, 765p), and HDTV (720p, 1080i,
1080p) YPbPr component video inputs. The TVP7002 also supports A/D conversion and color space conversion
of all standard PC graphics formats (RGB) from VGA up to UXGA.
A summary of the analog video standards supported by the TVP7002 module is show in Table 1.

Analog Input Clamping
The TVP7002 provides dc restoration for all analog video inputs including the SOG slicer inputs. The dc
restoration circuit (a.k.a. clamp circuit) restores the ac-coupled video signal to a fixed dc level. One dc
restoration circuit is implemented prior to each of the three ADC, and a fourth one is located prior to the SOG
slicer. The dc restoration circuit can be programmed to operate as either a sync-tip clamp (a.k.a. coarse clamp)
or a back-porch clamp (a.k.a. fine clamp). The sync-tip clamp always clamps the video sync-tip level near the
bottom of the ADC range. The back-porch type clamp supports two clamping levels (bottom-level and mid-level)
that are selectable using bits 0, 1, and 2 of register 10h. When using the fine bottom-level clamp, an optional
300-mV common-mode offset may be selected using bit 7 of register 2Ah.
In general, the analog video input being used for horizontal synchronization purposes should always use the
sync-tip clamp; all other analog video inputs should use the back-porch clamp. The advantage of the back-porch
clamp is that it has negligible video droop or tilt across a video line.

The selection between bottom- and mid-level clamping is performed by I2C subaddress 10h (see
Sync-On-Green Threshold). The fine clamps must also be enabled via I2C register 2Ah for proper operation. The
internal clamping time can be adjusted using the I2C clamp start and width registers at subaddress 05h and 06h,
respectively (see Clamp Start and Clamp Width).

Programmable Gain Control
The TVP7002 provides a 4-bit coarse analog gain control (before A/D conversion) and an 8-bit fine digital gain
control (after A/D conversion). The coarse analog gain and the fine digital gain are both independently
programmable for each ADC channel.
Coarse Gain Control
The 4-bit coarse analog gain control has a 4:1 linear gain control range defined by the following equation.
Coarse Gain = 0.5 + NCG/10, where 0 ≤ NCG ≤ 15
0.5 ≤ Coarse_Gain ≤ 2.0
Default: NCG = 7 (Coarse_Gain = 1.2)
The 4-bit coarse gain control can scale a signal with a voltage-input compliance of 0.5-Vpp to 2-Vpp to a
full-scale 10-bit A/D output code range. The minimum gain corresponds to a code 0h (2-Vpp full-scale input,
–6-dB gain) while the maximum gain corresponds to code Fh (0.5-Vpp full-scale, +6 dB gain). The 4-bit coarse
gain control is independently controllable for each ADC channel (Red Coarse Gain, Green Coarse Gain, and
Blue Coarse Gain).
Fine Gain Control
The 8-bit fine digital gain control has a 2:1 linear gain control range defined by the following equation.
Fine Gain = 1.0 + NFG/256 where 0 ≤ NFG ≤ 255
1.0 ≤ Fine Gain < 2.0
Default: NFG = 0 (Fine Gain = 1.0)
The 8-bit fine gain control is independently controllable for each ADC channel (Red Fine Gain, Green Fine Gain,
and Blue Fine Gain). For a normal PC graphics input, the fine gain is used mostly.
Programmable Offset Control
The TVP7002 provides a 6-bit coarse analog offset control (before A/D conversion) and a 10-bit fine digital offset
control (after A/D conversion). The coarse analog offset and the fine digital offset are both independently
programmable for each ADC channel.
Coarse Offset Control
A 6-bit code sets the coarse offset (Red Coarse Offset, Green Coarse Offset, Blue Coarse Offset) with individual
adjustment per channel. The coarse offset ranges from –32 counts to +31 counts. The coarse offset registers
apply before the ADC.
Fine Offset Control
A 10-bit fine offset registers (Red Fine Offset, Green Fine Offset, Blue Fine Offset) apply after the ADC. The fine
offset ranges from –512 counts to +511 counts.

Automatic Level Control (ALC)
The ALC circuit maintains the level of the signal to be set at a value which is programmed at fine offset I2C
register. It consists of pixel averaging filter and feedback loop. This ALC function can be enabled or disabled by
the I2C register at subaddress 26h.
The ALC circuit needs a timing pulse generated internally but the user should program the position properly. The
ALC pulse must be positioning after the clamp pulse. The position of ALC pulse is controlled by ALC placement
I2C register at address 31h. This is available only for internal ALC pulse timing. When using an external clamp
pulse, the fine clamp and the ALC both start on the leading edge of the external clamp pulse. Therefore, it is
recommended to keep the external clamp pulse as long as possible.
Analog-to-Digital Converters (ADCs)
All ADCs have a resolution of 10 bits and can operate up to 165 MSPS. All A/D channels receive an identical
clock from the on-chip phase-locked loop (PLL) at a frequency between 12 MHz and 165 MHz. All ADC
reference voltages are generated internally. Also the external sampling clock can be used.
Horizontal PLL
The horizontal PLL generates a high-frequency internal clock used by the ADC sampling and data clocking out
to derive the pixel output frequency with programmable phase. The reference signal for this PLL is the horizontal
sync signal supplied on the HSYNC input or from extracted horizontal sync of the sync slicer block for
embedded sync signals. The horizontal PLL consisted of phase detector, charge pump, loop filter, voltage
controlled oscillator (VCO), phase select, feedback divider, and post divider. The horizontal PLL block diagram is
shown in Figure 3.

The COAST signal is used to allow the PLL to keep running at the same frequency, in the absence of the
incoming HSYNC signal or disordered HSYNC period. This is useful during the vertical sync period, or any other
time that the HSYNC is not available.
There are several PLL controls to produce the correct sampling clock. The 12-bit feedback divider register is
programmable to select exact multiplication number to generate the pixel clock in the range of 12 MHz to
165 MHz. The 3-bit loop filter current control register is to control the charge pump current that drives the
low-pass loop filter. The applicable current values are listed in the Table 3.

The purpose of the 2-bit VCO range control is to improve the noise performance of the TVP7002. The frequency
ranges for the VCO are shown in Table 3. The phase of the ADC sample clock generated by the horizontal PLL
can be accurately controlled in 32 uniform steps over a single clock period (360/32 = 11.25 degrees phase
resolution) using the phase select register located at subaddress 04h.
The horizontal PLL characteristics are determined by the loop filter design, the PLL charge pump current, and
the VCO range setting. The loop filter design is shown in Figure 4. Supported settings of VCO range and charge
pump current for VESA standard display modes are listed in Table 3.

NOTE:
Selection between the 30-bit 4:4:4 output format and the 20-bit 4:2:2 output format is made
using bit 1 of register 15h.
Multiplexed CbCr data is output on BOUT [9:0] in the 20-bit 4:2:2 output format.
4:4:4 to 4:2:2 conversion is implemented after RGB to YCbCr color space conversion.
Sync Processing
Horizontal Sync Selection
The TVP7002 provides two HSYNC inputs and three analog SOG inputs for HDTV and PC graphics inputs. The
sync input used by the horizontal PLL is automatically selected based on activity detection.

SLES206 – MAY 2007
Sync Slicer
TVP7002 includes a circuit that compares the input signal on Green channel to a level 150 mV (typical value)
above the clamped level (sync tip). The slicing level is programmable by I2C register subaddress at 10h. The
digital output of the composite sync slicer is available on the SOGOUT pin.
Noise Immunity
In general, noise on a slowly varying input signal (i.e., sync falling edge) may cause a voltage comparator to
false trigger as the input passes through the linear range of the comparator. To improve the overall performance
of the TVP7002 sync slicer in the presence of noise on the SOG input, the voltage comparator includes
hysteresis. Maintaining a 50% slice level using the I2C programmable slice level control can further improve the
noise immunity of the Sync slicer. The slice level is programmable in 11.2-mV increments over a 350-mV range
as follows.
slice_level = (350 mV) × (NTH/31)
where 0 ≤ NTH ≤ 31, default: 11
0 ≤ slice_level ≤ 350 mV
Glitch Immunity
During white to black transitions, the input video waveform may undershoot below the sync slicer threshold. To
help attenuate the amplitude of such glitches, a single-pole low-pass filter with three selectable cutoff
frequencies (2.5, 10, and 33 MHz) is provided at the input of the SOG voltage comparator circuit. This filter is
bypassed in the default mode.
NOTE:
Although the low-pass filter may attenuate the amplitude of glitches present on the
SOG input, it also makes the sync falling edge less sharp.
Sync Separator
The sync separator automatically extracts VSYNC and HSYNC from the sliced composite sync input supplied at
the SOG input. The G or Y input containing the composite sync must be ac coupled to the SOG input pin using
a 1-nF capacitor. Support for PC graphics, SDTV, EDTV, and HDTV up to 1080p is provided.
Sync Activity Detection (Informative)
The TVP7002 provides activity detection on the sync inputs (VSYNC, HSYNC) to enable the host processor to
determine whether the PC graphics source is configured as a 3-wire, 4-wire, or 5-wire interface as defined here:
• 5 wire (G, B, R, HSYNC, VSYNC)
• 4 wire (G, B, R, CSYNC)
• 3 wire (G, B, R with SOG)
If activity is detected on the VSYNC input, the host processor should assume that the PC graphics input is
configured as a standard 5-wire interface. In this case, the HSYNC input of the TVP7002 should be configured
as an HSYNC input.
If activity is detected on the HSYNC input but not on the VSYNC input, the host processor should assume that
the PC graphics input is configured as a standard 4-wire interface. In this case, the HSYNC input of the
TVP7002 should be configured as a CSYNC input. The TVP7002 supports the following two types of CSYNC
inputs.
CSYNC = VSYNC XOR HSYNC (default)
CSYNC = VSYNC OR HSYNC

If activity is not detected on either the HSYNC input or the VSYNC input, the host processor should assume that
the PC graphics input is configured as a standard 3-wire interface. In this case, the TVP7002 is automatically
configured for a SOG input.

The activity detection status for the VSYNC and HSYNC inputs is written to the I2C status register at subaddress
14h.
NOTE:
Pin 13 of a standard 15-pin VGA video connect can be either a horizontal sync
(HSYNC) or a composite sync (CSYNC).
NOTE:
For component video inputs, the active HSYNC and VSYNC should always be
derived from the selected SOG input. This can most easily be ensured by setting the
AHSO, AVSO, AHSS and AVSS bit fields in register 0Eh to logic 1.
NOTE:
For proper operation when separate HSYNC and VSYNC inputs are used, the
leading edge of VSYNC must not be presicely aligned with the leading edged of
HSYNC. A simple RC delay circuit will provide adequate delay in most applications.

Embedded Syncs
Standard with embedded syncs insert 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 5 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

The insertion location of the SAV/EAV codes on a video line is programmable using the AVID start/stop pixel
values located at subaddresses 40h through 43h.
NOTE:
When enabled (bit 0 of subaddress 15h), embedded syncs are present in both the Y
and C outputs.
Output Range Limits
The TVP7002 provides selectable output range limits in I2C subaddress 15h:
00 = RGB coding range (Y, Cb, and Cr range from 0 to 1023) (default)
01 = Extended coding range (Y, Cb, and Cr range from 4 to 1019)
10 = ITU-R BT.601 coding range (Y ranges from 64 to 940, Cb and Cr range from 64 to 960)
11 = Reserved
NOTE:
RGB coding range not allowed with embedded syncs.
Power Management
The TVP7002 supports both automatic and manual power-down modes. The automatic power-down mode can
be selected by setting bit 2 of subaddress 0Fh to logic 0.
In the automatic power-down mode, the TVP7002 powers down the ADCs, the ADC reference, and horizontal
PLL when activity is not detected on both the selected HSYNC input and the selected SOG input (VSYNC is no
longer used). The TVP7002 restores power whenever activity is detected on either the selected HSYNC input or
the selected SOG input.
The TVP7002 can also be placed in power down mode via the active high PWDN input (pin 70). When the
PWDN input is driven high, the TVP7002 powers down everything including the I2C interface and the digital
outputs are not placed in a high-impedance mode.
The TVP7002 can also be placed in a power down mode using bit 1 of register 0Fh.
Individual blocks of the TVP7002 can be independently powered down using register 2Bh.

I2C Host Interface
Communication with the TVP7002 device is via an I2C host interface. The I2C standard consists of two signals,
serial input/output data (SDA) line and 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
multi-mastered, the TVP7002 can function as a slave device only.
Since SDA and SCL are kept open-drain at logic high output level or when the bus is not driven, the user should
connect SDA and SCL to a positive supply voltage via a pullup resistor on the board. SDA is implemented
bidirectional. The slave addresses select, terminal 73 (I2CA), enables the use of two TVP7002 devices tied to
the same I2C bus, as it controls the least-significant bit of the I2C device address

Reset and I2C Bus Address Selection
TVP7002 can respond to two possible chip addresses. The address selection is made at reset by an externally
supplied level on the I2CA pin. The TVP7002 device samples the level of terminal 73 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.

Power Up, Reset, and Initialization
No specific power-up sequence is required, but all power supplies should be active and stable within 500 ms of
each other. Reset may be low during power up, but must remain low for at least 1 µs after the power supplies
become stable. Alternatively, reset may be asserted any time with minimum 5-ms delay after power-up and must
remain asserted for at least 1 µs. Reset timing is shown in Figure 7. It is also recommended that any I2C
operation starts 1 µs after reset ended. Table 8 describes the status of the TVP7002 terminals during and
immediately after reset.

applications using TI components. To minimize the risks associated with customer products and applications, customers should
provide adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask
work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services
are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such
products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under
the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of information in TI data books or data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an
unfair and deceptive business practice. TI is not responsible or liable for such altered documentation.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service
voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business
practice. TI is not responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would
reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement
specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications
of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related
requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any
applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its
representatives against any damages arising out of the use of TI products in such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is
solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in
connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products
are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any
non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
