Q: Many reference designs recommend not using a programmable part, why? A: The primary reason is the JITTER performance of the programmable oscillators that our competitors manufacture exceed 300 pS of pk - pk jitter. The Cardinal products are significantly better, they meet the Belcore spec of <100 pS. Cardinal: pk-pk jitter < 80 pS at 1,000,000 cycles (CPPL, CPPFX, CPPD) Cardinal: rms jitter < 9 pS at 1,000,000 cycles (CPPL, CPPFX, CPPD).
