LDC1312: X-tal oscillator for CLKIN

Part Number: LDC1312


My customer would like to use either SG-210STF 40.0MHz L, SG-8101CG 40.0MHz TJHSA or SG-8018CG 40.0MHz TJHSA for LDC1312 CLKIN input. I attach the datasheets of them.
Could all of them be used as a CLKIN input?
Though jitter specs are a bit different among them, are there any jitter spec to meet as a CLKIN input?

Best regards,


  • Hello, 

    Any of these clock options can be used. There is not a required jitter spec for the LDC1312 but the better the jitter spec, the better performance of the LDC. Additionally, minimizing the temperature variation of the clock frequency gives more consistent performance of the LDC over over temperature. For reference, the internal oscillator has a -13ppm/C temperature coefficient.
