4-CH WD1 (960H)/D1 Compatible Video Decoders
and Audio Codecs
TW2964
Features
Video Decoder
WD1 (960H) and D1 compatible video decoding
operation and it is programmable each channel
NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N
combination), PAL (60) support with automatic
format detection
Software selectable analog inputs allows any of 2
CVBS per one video ADC
Built-in analog anti-alias filter
Four 10-bit ADCs and analog clamping circuit for
CVBS input
Fully programmable static gain or automatic gain
control for the Y channel
Programmable white peak control for CVBS
channel
4-H adaptive comb filter Y/C separation
PAL delay line for color phase error correction
Image enhancement with peaking and CTI
Digital sub-carrier PLL for accurate color decoding
Digital Horizontal PLL for synchronization
processing and pixel sampling
Advanced synchronization processing and sync
detection for handling non-standard and weak
signal
Programmable hue, brightness, saturation,
contrast, sharpness
Automatic color control and color killer
ITU-R 656 like YCbCr (4:2:2) output or time
multiplexed output with 36/72/144MHz for WD1
or 27/54/108MHz for D1 format
Audio Codec
Integrated five audio ADCs processing and one
audio DAC
Provides multi-channel audio mixed analog output
Support I2S/DSP Master/Slave interface for
record output and playback input
PCM 8/16-bit and u-Law/A-Law 8-bit for audio
word length
Programmable audio sample rate that covers
popular frequencies of 8/16/32/44.1/48kHz
Miscellaneous
Two-wire MPU serial bus interface
Integrated clock PLL for 144/108MHz clock
output
Power save and Power down mode
Low power consumption
Single 27MHz crystal for all standards and both
WD1 and D1 format
I/O Pin compatible with TW2960 (Supply pins are
different)
3.3V tolerant I/O
1.0V/3.3V power supply
100-pin and 128-pin LQFP packages
