Hi,
I am looking for possible solutions to be able to phase shift a
signal in the 1 to 4 MHz range by a certain amount between 0 and 180
deg. Originally we were using the AD9501 delay chip but they are going
obsolete. The resolution should be less or equal to 50ps over the
above frequency range.
Some solutions that we have already come up with are
1) using FPGA with DCMs to induce the phase shift. <-- This might not
be realizable at that resolution.
2) Use FPGA to control a DDS and produce the phase shift. <-- Best
solution we have right now but we have never tested it.
3) Substitute the AD9501 with MC10EP195 <-- The ECL voltage levels
might need to be converted to lvcmos/lvttl
I am looking for other possible external solutions. An FPGA would be
controlling the phase shifting. I figured people who work with this
kind of stuff on a daily basis might know. Thanks a lot for any
answer,
Amish
