Multi-Rate SerDes Transceiver for IEEE 1394b Applications

This paper presents the implementation of a multi-rate SerDes transceiver for IEEE 1394b applications. Simple and effective pre-emphasis and equalizer circuits are used in the transmitter and receiver, respectively. A phase interpolator based clock and data recovery circuit with optimized linearity is also described. With an on-chip fully integrated phase locked loop, the transceiver works at data rates of 100 Mb/s, 400 Mb/s, and 800 Mb/s, supporting three different operating modes of S100b, S400b, and S800b for IEEE 1394b. The chip has been fabricated using 0.13 μm technology. The die area of transceiver is 2.9×1.6 mm2 including bonding pads and the total power dissipation is 284 mW with 1.2 V core supply and 3.3 V input/output supply voltages.
