MSM7660 Overview
The MSM7660 is a decoder which converts digitally sampled NTSC or PAL video signals to the format based on ITU-RBT601. The MSM7660 can accept posite video and S video signals. For posite signals, the MSM7660 converts signals to YUV data via a 2-dimensional Y/C separation circuit.
MSM7660 Key Features
- Accepts posite video and S video signals
- patible with NTSC/PAL
- 2-dimensional Y/C separation using adaptive b filter (this filter is bypassed for S video signal input) NTSC: 3 lines/2
- Sampling frequency 14.75 MHz (PAL Square Pixel) 14.31818 MHz (NTSC 4Fsc) 12.27 MHz (NTSC Square Pixel) 13.5 MHz (ITU-RS6
- Internal AGC/ACC circuit
- 8-bit Y/C (CbCr) output (conforms to ITU-RBT601) YCbCr: 4:2:2 YCbCr: 4:1:1
- High impedance output possible, priority cascade control function
- I2C-BUS interface
- External terminal mode (default) or internal register mode can be selected for operation mode setting
- A frequency one or two times the sampling clock is supplied to LSI
