SLES135A
3.1.6 A/D Converters
All ADCs have a resolution of 11 bits and can operate up to 60 MSPS. All A/D channels receive an identical
clock from the on-chip, phase-locked loop (PLL) at a frequency between 24 MHz and 60 MHz. All ADC
reference voltages are generated internally.
3.2
Digital Video Processing
This block receives digitized video signals from the ADCs and performs composite processing for CVBS and
S-Video inputs, YCbCr signal enhancements for CVBS and S-Video inputs. It also generates horizontal and
vertical syncs, and other output control signals such as RTC 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/discrete syncs. The circuit detects pseudo sync 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.BT656 output as ancillary data or stored in an internal FIFO for retrieval via the
I2C interface.
3.2.1 2x Decimation Filter
All input signals are typically oversampled by a factor of 4 (54 MHz). The A/D outputs first pass through
decimation filters that reduce the data rate to 1x 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.
3.2.2 Composite Processor
The TVP5160 digital composite video processing circuit receives a digitized composite or S-Video signal from
the ADCs and performs 2D or 3D Y/C separation (bypassed for S-Video input), chroma demodulation for
PAL/NTSC and SECAM, and YUV signal enhancements.
3.2.3 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.
3.2.4 Y/C Separation
Y/C separation may be done using 3D or 2D 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 notch filters are used. 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.
3.2.5 3D Frame Recursive Noise Reduction
The TI proprietary frame recursive noise reduction or 3DNR reduces the level of noise in CVBS, S-Video, or
component inputs by comparing multiple frames of data and canceling out the resulting noise. The 3DNR
utilizes the same frame buffer memory used by the 3DYC. The 3DNR may function concurrently with 3DYC.
There are various modes of operation for the 3DNR and 3DYC:
MODES

MEMORY REQUIRED
Mode 0
3DYC + 3DNR
4 MBytes
Mode 1
3DYC only
