MSM7661B Description
The MSM7661B is an LSI device which converts digitally sampled NTSC or PAL video signals to 8-bit format based on ITU-RBT601. The input video signals available are posite video signals and S video signals. The posite video signals are converted to YUV data via a 2-dimensional Y/C separation circuit.
MSM7661B Key Features
- 2-dimensional Y/C separation using adaptive b filter (this filter is bypassed for S video signal input) NTSC: 3 lines/2
- Input signal synchronization can lock synchronization and color burst at high speed through internal digital processing.
- Internal AGC/ACC circuit Switchable between AGC and MGC (fixed gain) n Switchable between ACC and MCC (fixed gain)
- Built-in decimation filter located in the input stage allows easy configuration of an external filter circuit (located a
- Automatic NTSC/PAL recognition (only for ITU-RBT.601)
- Sleep mode 1/42
- Multiplex signal recognition (Teletext) Data during vertical blanking is output in 8 bits in Through mode. ° I2C-bus int
- 3.3 V single power supply (each I/O pin is 5 V tolerable)
- Package: 64-pin plastic QFP (QFP64-P-1414-0.80-BK) (Product name: MSM7661B GS-BK)
