Serial Control Interface
The TQM8M9076 has a CMOS SPI
input stream to parallel output word. The input is 3-wire (CLK, LE and SERIN) SPI
serial control interface resets device attenuation state to 31.5dB. The 6-bit SERIN word is loaded into the register on rising
edge of the CLK, MSB first. When LE is high, CLK is disabled.
SERIN (MSB in First 6-Bit Word) Control Logic Truth Table
LSB
Any combination of the possible 64 states will provide an attenuation of approximately
the sum of bits selected
Test conditions: 25ºC, V
