Hello,

Is there an internal resistance on xin pin of HX2 ?

If yes, which is pull-up or pull-down?

Please tell me the value of resistance in that case.

Also, when the HX2 is turn-off, is the voltage level of xin pin low(grounded)?

Best regards,

Takahashi

As per the datasheet, XIN and XOUT have neither pull-up or pull-down because there is no description about RDN or RUP.

Internal clock circuit for XIN and XOUT is constructed a basic clock circuit (it has amplifier and Rfb). Unfortunately, we are not offering the circuit in public.

If the customer just complies with "3.2 Crystal Requirements" on AN72332, crystal can work.

Best regards,
