DAC3164 SYNCP / SYNCN Signal

Other Parts Discussed in Thread: DAC3164

From a customer:

"We would like a clarification regarding the DAC3164 which we are incorporating into one of our new designs. I understand that the SYNCP/SYNCN signal is to be used for multichip synchronization. Since we will only have one chip per design, is it possible to tie this signal to its inactive state?”

Hi,

From the datasheet, page 37:

Note: When ALIGNP/N are not used, it is recommended to clear the alignrx_ena register (config1, bit 4), and tie ALIGNP to DIGVDD18 and ALIGNN to GROUND. When SYNCP/N are not used, it is recommended to clear register syncrx_ena (config0, bit3), and the unused SYNCP/N pins can be left open or tied to GROUND.

So the SYNC signal need not be used where synchronization is not required.

Regards,

Richard P.
