• Completely synchronous interface (interface signals are fixed on ascending front)

• RX clock computation scheme (detection up to 800Mbit/s)

• LoopBack included

• The ratio of local and reception frequencies is 1:6

• Small number of triggers working on TX and RX clock

MCK-0116–channel SpaceWire routing switch

• Supports signal, symbol, exchange, packet, network protocol stack levels• Advanced non-blocking internal switching fabric• Supports adaptive routing• Supports multicast routing• Provides time-codes distribution in compliance with the ECSS-E-50-12A

SpaceWire standard• Provides interrupt codes and poll codes distribution in compliance with the

project of the second part of the ECSS-E-50-12A SpaceWire standard• Includes the internal RISC core for configuration, monitoring and network

administration purposes

Interfaces:

– 16 full-duplex SpaceWire interfaces– Transmission rate of each interface from 5 Mb/s to 400 Mb/s;

can be set independently for every of 16 links– Parallel interface to external static memory– Parallel SRAM-like interface to external RISC processor

(includes masked interrupt signal)
