Product Number: HMC7044
Hello,
I want to implement a clock distribution system for data converters, here is my setup:
- A source produces two free running clocks at 1 GHz (CLK) and 1 MHz (SCLK), they are generated together so they have know and fixed phase relation
- An HMC7044 is connected to the source
- An FPGA can control the HMC digital inputs
The goal is to have deterministic phase relations between a specific SCLK edge and the output clocks of the HMC7044.
My idea is to do the following:
1) Power up the HMC, CLK and SCLK generation is already stable
2) Turn on RFsync buffer on the HMC to synchronize the internal SYSREF timer with the SCLK signal
3) Disable RFsync buffer, from now on local SYSREF is synchronized with SCLK
4) The FPGA, also connected to SCLK, chooses a specific rising edge and drives the GPI pin to 1 and then to 0 to enable a reseed request
Q: Is it possible to do so?
At the moment I observe the following:
After step 2 and 3, the fpga chooses a rising edge every ms and I see that there is fixed phase alignment between HMC outputs and SCLK an the input at every reseed request
If I repeat steps 2 and 3, then there is again a fixed phase alignment but this is different from the previous value.
