DS25C400
Description
The DS25C400 is a four-channel serializer/deserializer (SERDES) for high-speed serial data transmission over controlled impedance transmission media such as a printed circuit board backplane or twin-axial cable. It is capable of transmitting and receiving serial data of 2.125
- 2.5 Gbps or 1.0625
- 1.25 Gbps per channel. Each transmit section of the DS25C400 contains a low-jitter clock synthesizer, an 8-bit or 10-bit parallel to serial converter with built in 8b/10b encoder, and a CML output driver with selectable pre-emphasis optimized for backplane applications. Its receive section contains an input limiting amplifier with on-chip terminations and selectable equalization levels, a clock/data recovery PLL, a ma detector and a serial to parallel converter with built-in 8b/10b decoder. The DS25C400 has built-in local loopback test mode, pseudo-random pattern generator and error detector to support self-testing. The DS25C400 requires no external ponents for its clock...
