MSM7652

• Black & Blank Pedestal

This block adds sync signals at the luminance side to luminance signals.

• Interpolator + LPF

This block executes data interpolation and the elimination of high frequency components by

LPF for input chrominance signals.

•I2C Control Logic

This is the serial interface block based on I2C standard of Phillips Corporation.

Internal registers MR and CR can be set from the master side.

When writing to the internal registers other than MR [1] (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 [1] and CR [1:0].

• Sync Generator & Timing Controller

This block generates sync signals and control signals.

This block operates in slave mode, which performs external synchronization, and in master

mode, which internally generates sync signals.

• Color Burst Generator

Outputs U and V components of amplitude of burst signals.

• Subcarrier Generator

Executes color subcarrier generation.

• Interpolation Filter (IPF)

This block performs upsampling at CLKX2 for luminance signals and chrominance signals

modulated with CLKX1 divided from CLKX2. Interpolation processing is executed in this

process.

• Closed Caption Block

This block generates the signal for closed caption.
