2.1.6
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.
2.2
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.
2.2.1
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 1
× 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
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.
2.2.3
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.
