The TNETE2201 gigabit ethernet transceiver is the derivative of Texas Instruments’ proven Fibrechannel technology enhanced to run at 1.25 Gbps. The device is designed for ultra high speed bi-directional point-to-point data transmission over controlled impedance media of approximately 50 to 70 Ohms.

The device performs the data serialization and de-serialization function for the gigabit ethernet physical layer interface. The serializer/transmitter accepts 8b/10b parallel encoded data bytes. The parallel data bytes are serialized and transmitted differentially nonreturn-to-zero at pseudo-ECL (emitter coupled logic) voltage levels. The de-serializer/receiver extracts clock information from the input serial stream and de-serializes the data, outputting a parallel 10-bit data byte with respect to two receive byte clocks. The TNETE2201 also features an internal loopback capability for self-test purposes.

With its low cost, high data rate (1.25 Gbps), and compatibility, the TNETE2201 is designed to address the requirement for the next generation differential line interface circuits in the high speed networking sector such as switch-to-switch links, switch-to-server links, and backbone applications.

The TNETE2201 is available in a 64-pin thermally enhanced thin quad flat pack PJD (10mm x 10mm) or PHD (14mm x 14mm).

End user applications:
