Re: [Discuss-gnuradio] USRP1 XCV2450 LO - can it be bypassed with the motherboard's LO

[Matt Ettus]

Each XCVR2450 is already locked to the motherboard crystal.  But "bypass it with the motherboard's
X-TAL source" does not make sense.  The LO is generated by locking to the motherboard crystal source.  No bypassing is necessary.

Hello,

 we have a USRP1 with 2 XCVR2450 daughtercards. Each XCVR2450 has its
own LO however , we would like to bypass it with the motherboard's
X-TAL source.
Both XCVR2450 daughtercards will then be driven synchronously by the
motherboard.

Is this possible ?   If so, is there a schematic of the XCVR2450 and
motherboard which will show the required jumpers and/or SMTs ?

If not, which USRP (2 ? ) and daughtercards do we  need ?

Thank you,
