Texas Instruments DS25C400
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.| Part No. | DS25C400 |
