2. Horizontal Readout

In this IC, the readout and write clocks are asynchronous.

The readout 1H sample coefficient is set by H SZ RD.

An HOUT pulse with a pulse width of 68ck is output from horizontal readout reference pulse HRSP (internal

pulse).

Readout start timing is set by H PHASE.

The HBLK pulse set by LFT BLK and RGT BLK is output. However, this pulse does not stop readout, so it has

no relation to the actual blanking interval.
