Function

Clock select input. This pin selects the frequency of the CLK input. If CLK is 1.536 MHz, set

CLKSEL = 1. If CLK is 1.544 MHz, set CLKSEL = 0. Pin has an internal pullup resistor to VCC.

Serial input data. Digital input that contains serial data word which controls the filter frequency

response setting.

Output latch clock. Digital input which loads the data word back into the shift register from the latch.

Shift clock. Digital input which shifts the serial data on SID into the shift register on rising edges and

out onto SOD on falling edges.

Serial output data. Digital output of the shift register.

Master clock input. Digital input which generates clocks for the switched capacitor filters.

Frequency can be either 1.544 MHz or 1.536 MHz.

Digital ground. 0 volts. All digital inputs and output are referenced to this ground.

Input latch clock. Digital input which loads data from the shift register into the latch.

Negative supply. –5volts ±10%.

Analog input.

Analog ground. 0 volts. Analog input and output are referenced to this ground.

Analog output.

Powerdown input. When PDN = 1, device is in powerdown mode. When PND = 0, device is in normal

operation. This pin has an internal pulldown resistor to GND.

Positive supply. 5 volts ± 10%
