A 43Gb/s full-rate clock transmitter in 0.18μm SiGe BiCMOS technology
Abstract
A 43-Gb/s full-rate clock transmitter chip for SONET OC-768 transmission systems is reported. The IC is implemented in a 0.18μm SiGe BiCMOS technology featuring 120GHz f T and 100GHz f max HBTs. It consists of a 4:1 multiplexer, a clock multiplier unit and a frequency lock detector. The IC features a clock jitter generation of 260fs rms and dissipates 2.3 W from a - 3.6V supply voltage. Measurement results are compared to previously reported half-rate clock transmitter designed using the same technology. © 2004 IEEE.
