Part Number: LMH1983


I've designed in the LMH1983 + LMH1981 to generate my 148.5MHz for an HD-SDI interface with a GS2972 SemTech device.

Currently I have design in the CTS 27MHz VCXO recommended in the datasheet/app note, but it's very large and would like to source a smaller alternative. I'm considering an Epson VG-4231CE 27MHz stability 37ppm APR 100ppm and I beleive the Jitter is 50ps maximum. It's onlys 3.2x2.5mm. Is this part suitable?

Thanks, Paul
