If you have to have something pre-integrated and soon, I'd look at Meinberg: http://www.meinberg.de/english/products/index.htm#network_sync
We have several Meinbergs, quality hardware definitely. But I really wish they'd have hardware timestamping. And 1GE instead of 100M would also reduce jitter further. Right now I'm seeing offset of about 65us from our meinbergss over routed network of several hops and delay to meinbergs ranging from 0.5ms to 8.4ms I wonder if symmetricom does NTP timestamping in HW, or only PTP? -- ++ytti
