Modified LDO regulator sinks PECL-termination current Design How-To 6/28/2005 Post a comment For high-speed clock and data systems, positive emitter-coupled-logic (PECL) - a differential signaling scheme - is emerging as a preferred alternative to single-ended CMOS and TTL logic. High-speed ECL offers differential I/O, with excellent skew and jitter control, along with fast rise and fall times. From the June issue of Planet Analog magazine, a Maxim engineer shows how to extract high current.
