Multi-Channel DPLL/DCO - Two/Eight Channels

The 8A34045 multi-channel Digital PLL/Digitally Controlled Oscillator (DPLL/DCO) provides tools to manage timing references, clock conversion, and timing paths for common communications protocols such as Synchronous Ethernet (SyncE), Optical Transport Network (OTN), and Common Public Radio Interface (CPRI). The device can be used to synchronize communication ports on line cards or daughter cards that are connected with synchronization sources across backplanes or other media. DCOs are available to be controlled by OTN clock recovery servo software running on an external processor. DPLLs support the filtering of gapped clocks for OTN; and hitless reference switching between references from redundant timing sources. The device supports multiple independent timing channels for clock generation, jitter attenuation, and universal frequency translation. 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.
