... This outputs serial data to the DAC. 7. Other Pins ZRESET (input) This is the LC895196 reset pin. The LC895196 is reset when this signal is low. This signal must be kept low for at least a period of 1 µs after power on. XTALCK0, XTAL0 These cause oscillation at 25 MHz or 27 MHz. Multiples of these respective clocks may also be input. Frequencies from the outside may also be input into XTALCK0 ...
