Hi Team,
Please help me to resolve problem.
We are using LMH1983 with differential output VCXO
Its amplitude is as high as 800 mV.
Referring the datasheet, XOIN+ and XOIN- can be used in
either single end or differential.
Q1. Does the device automatically distinguish single end or
differential input on XOIN+/- pin, or need to be program through
register 0x25 bit 2?
Q2. If the device automatically distinguishs the single end or differential
input on XOIN+/- pin, what criterion does the device uses?
Q3. If device requires register access to receive differential clock, how
can you realize register access?
Default register settings select single end input.
In order to change register, you need 27MHz clock however, to receive clock
You need register access.
Q4. If the device accepts both single end or differential input on XOIN+/- pin,
without auto detection circuit or register 0x25 bit 2, can the device work
with higher differential amplitude than 454 mV?
