The 8A34046 Synchronous Equipment Timing Source (SETS) for Synchronous Ethernet (SyncE) and Optical Transport Network (OTN) is a highly integrated timing device with four Digital PLL (DPLL) channels and four Digitally Controlled Oscillator (DCO) channels. The device integrates the timing blocks necessary to implement the SETS function as described in ITU-T G.8264.

The 8A34046 DPLL channels can be configured to comply with ITU-T G.8262 and G.8262.1 or as jitter attenuators; they can also be configured as DCOs. The DCO channels can be connected to a DPLL channel to supply additional outputs and frequencies for that DPLL; alternatively they can be controlled by external software or they can free run based on the local oscillator. The device can be used as a single timing and synchronization source for a system or two of them can be used as a redundant pair for improved system reliability. Input-to-input, input-to-output and output-to-output phase skew can all be precisely managed. The device outputs ultra-low-jitter clocks that can directly synchronize SERDES running at up to 28Gbps; as well as CPRI/OBSAI, SONET/SDH and PDH interfaces.
