CM106-F+/L+

High End 8CH DAC and 2CH ADC Integrated Solution

MCU to read them.

CM106F+/L+ has one input pin ‘SCLK’ to get serial clock from MCU, and one open-drain output

pin ‘SDAT’ to send or receive serial signal to/from MCU. As shown below, ‘SDAT’ should be

stable when ‘SCLK’ is high, and can have transition only when ‘SCLK’ is low.

START and STOP conditions shown below are the exception. Every transaction begins from a

START, and ends with a STOP, or another START (repeated START).

The figure below demonstrates a transaction example. After every 8 bits sent by the transmitter,

the receiver should send one bit low for positive acknowledgement or one bit high for negative

acknowledgement. After the negative acknowledgement, a STOP or repeated START should

follow.
