Dual 16-bit DAC: JESD204B interface; up to 1.25 Gsps
Description
usage depends on ts_mode:
Description
(dclk / ts_clkdiv)
Description
temperature sensor level selection
sets clock frequency temp_sensor_cntrl
sets number of wait cycles between measurements
ts_mode = “00”: applied directly to temp_sensor
ts_mode = “others”: sets threshold for temp_alarm
