ADC3241: SYSREF Termination

Ikechukwu Anyiam

Part Number: ADC3241

Hello team,

If SYSREF is not used on this part, what is the correct way to terminate the inputs? Is a 0.1uF to ground okay?

Regards,

Hi I.K.

If the SYSREF inputs will be unused, terminating them with 0.1uF capacitors to ground is acceptable.

Please ensure the SYSREF buffer is disabled, by setting Register 70Ah, Bit 0 = 1. (PDN SYSREF = 1).

Best regards,
