Radio Baseband
The radio basebasnd receive I/Q signal from
ADC,it includes sinc downsample,AGC(auto RF
gain and digital gain control) ,RSSI(receive signal
strength indicator) and channel filtering.
FM Demodulator
The FM demodulator includes channel selection,
FM demodulation,adaptive noise cancellation,
programmable de-emphasis(50/75 µs),bass boost,
volume control. Digital audio stream is converted into analog
througn DAC.
VSB Demodulator
The VSB demodulator is an AM Vestigial
Sideband demodulator for CVBS signal recovery.
format according to register-selected. It can be
divided into a luminance path and a chrominance
path. The luminance path first clamp the video
signal, then calibration to target level and through
a luma filter. The chrominance path has a color
subcarrier recovery unit to regenerate the color
subcarrier for any modulated chroma scheme and
then performs an AM demodulation for PAL and
NTSC and an FM demodulation for SECAM
according tow w w . D a t a S h e e t . c o . k r register-selected. YcbCr to ITU-601
interface is converted from YUV/YIQ/YRB .
.
ITU-601 Interface
The ITU-601 Interface is an ITU-601 compliant
8bit 4:2:2(YcbCr) parallel interface which include
dclk,hsync,vsync,data[7:0].dclk,hsync,vsync all
have polarity option. Below is the timing for the
bus:
PAL/NTSC/SECAM Decoder
The PAL/NTSC/SECAM decoder can handle
NTSC,PAL,SECAM, M,D,B,I,G,H,L,K in CVBS
