### Q: Is it possible to generate 10MHz clock from WR Switch?
|

|
|
A: Unfortunately it's not possible right now. WR Switch outputs only
|
|
A: Yes, it is possible with latest v3.4 version of the White Rabbit
|
|
62.5MHz clock signal. However, one can generate 10MHz aligned to WR time
|
|
Switch hardware and coming v4.2 firmware release. By default SMC
|
|
using the
|
|
connector *CLK2* produces 10MHz signal synchronous to the White Rabbit
|
|
|
|
clock. The *CLK2* frequency, ratio and delay to the 1-PPS output can be
|
|
|
|
configured by user to generate other clocks as well. Please check the WR
|
|
|
|
Switch manual for more details.
|
|
|
|
If you use one of the previous versions of the WR Switch hardware, you
|
|
|
|
can generate 10MHz using the
