• Manufacturer Part Number: msm7650
• Description: Ntsc/pal Digital Encoder
• Manufacturer: Oki Semiconductor

¡ Semiconductor
• Black & Blank Pedestal
• Interpolator +LPF
• I
• Sync Generator & Timing Controller
• Color Burst Generator
• Subcarrier Generator
• Interpolation Filter (IPF)
This block adds sync signals at the luminance side to luminance signals.
This block executes data interpolation and the elimination of high frequency components by
LPF for input chrominance signals. Both 4:2:2 and 4:1:1 signals are processed.
This is the serial interface block based on I
Internal registers MR and CR can be set from the master side.
When writing to the internal registers other than MR [5] (black level control) and CR [1:0]
(overlay level), written contents are immediately set to them. It is during the vertical blanking
period that written contents are set to MR [5] and CR [1:0].
This block generates sync signals and control signals.
This block is operated in slave mode, which performs external synchronization, and in master
mode, which internally generates sync signals.
Outputs U and V components of amplitude of burst signals.
Executes color subcarrier generation.
This block performs upsampling at CLK X 2 (double speed CLKX1) for luminance signals and
chrominance signals modulated with CLKX1. Interpolation processing is executed in this
process.
