PM6256

PM6256 is a multi-purpose Ethernet PHY supporting rates from 1 GbE to 800 GbE with a broad range of FEC regeneration and termination capabilities. It supports up to 800 Gbps capacity in retiming applications and up to 400G capacity in gearbox and 2:1 mux applications. The device features 16 SerDes, a hitless 2:1 mux and a flexible crosspoint.

Its SerDes can support backplanes and passive Direct Attach (DAC) cables at up to 106 Gbps and can also be configured to reduce power for VSR applications. The hitless 2:1 mux enables high availability architectures and the device latency is deterministic to enable Class C/D PTP at the system level.

Benefits

* 800 Gbps device enables high-density, 106G SerDes based line cards and fixed form factor switches * Multiple operating modes enable design reuse across platforms and improves time to market * Crosspoint enables flexible connection to multiple types of optics or datapaths on a single design * Deterministic latency enables PTP Class C/D at the system level * FEC termination and conversion capability enables support of a wide range of optical modules * Complete set of META-DX2 SDK APIs to reduce development time
