CDCE62002 Test Pin 19 - TEST_SYNC

Other Parts Discussed in Thread: CDCE62002

Hi,

For the CDCE62002 - if Pin 19 is tied to logic 1, hat is the effect on the CDCE62002 ?.

I was working to an earlier datasheet which was current at the time - there was no indication of what to do with this pin - hence tied high with 47k resistor.

Thanks and Regards,

Richard.

Hi Richard,

I previously mentioned that 47k resistor to pin 19 is o.k. I thought this pin is connected to GND. But it looks like you connected pin 19 to logic 1. This pin needs to be grounded.

Sorry for the confusion. You are right our datasheet did not have any specific recommendation for this pin. We showed the pin connection in our EVM user's guide (schematic).

Thanks,

Firoj
