SDATA
20 serial data input for the 4 control DACs (9-bit DAC for AGC gain, 8-bit DAC for frequency cut-off;
additional 8-bit DAC for OFD output voltage; 10-bit DAC for ADC clamp level and the standby mode
per block and edge pulse control); see Fig.3, Fig.4 and Table 1
SCLK
21 serial clock input for the control DACs and their serial interface; see Fig.3, Fig.4 and Table 1
