E. Yeung, M. Horowitz
Stanford Univ., Stanford, CA

An 8b wide single-ended simultaneous bidirectional transceiver test chip in 0.4 um CMOS permits study of the major challenges in high-performance, low-cost parallel-link design. Each pin contains on-chip voltage samplers to measure link internal voltage margins, and per pin timing adjustment to compensate for inter-bit skew and to measure timing margins.


15.6 A Scalable 32Gb/s Parallel Data Transceiver with
On-Chip Timing Calibration Circuits

HotRail, Inc., San Jose, CA

A parallel data transceiver provides point-to-point interconnect between chips. Data transfer rate per differential pair is 1.6Gb/s. An on-chip timing calibration circuit performs data de-skewing and timing optimization. The macro consumes <400mW with <8ns latency and <10 -15 BER. In 0.25 um CMOS and measures 2500x700 um2 using BGA or QFP packages. Built-in self test (BIST) logic is implemented for product testing.
