Serial Interface Circuit
The IR3Y38M has a serial interface to control the
gain of the AGC amplifier and the offset of the
blanking level. This interface is constituted by a shift
register for serial-parallel conversion, data registers
and D/A converters.
The data input to SDATA is fetched and shifted at
the rising edge of the SCK. While transmitting data,
the SDATA must be low when the SCK falls. When
the SDATA is high and the SCK falls, the data on
the shift register is stored at the selected data
register at the following falling edge of the SDATA.
The stored data register is selected by the data of
the D
0
and D
1
bits.
