Abstract :
A 0.13/spl mu/m 1.2V GTL bus interface with compensated slew rate and termination achieves 400MT/s at a 6.4GB/s data rate in a 5-load MP environment. Packaged on an FCBGA and interposer with 5:1:4 signal to power and ground ratio and routed on 12mm 45/spl Omega/ traces, the interface incorporates I/O timing self test supported by a DLL and an interpolator with 25ps peak-to-peak jitter.
