emitter-coupled logic [i′mid·ər ¦kəp·əld ′läj·ik]

The positive emitter-coupled logic (PECL) differential outputs achieve full swing at the minimum specified input signal.
7, 2003 The NBSG72A extends the GigaComm(TM) family to include a crosspoint switch with two inputs feeding two outputs that operates above 7 GigaHertz Extending its industry leadership position in the high-speed Positively Referenced Emitter-Coupled Logic (PECL) market, ON Semiconductor (Nasdaq:ONNN) today introduced the NBSG72A -- a Silicon Germanium (SiGi) based, high bandwidth, fully differential crosspoint switch with output level select capabilities.
With both design flexibility and HSTL inputs, the MC100EP809 can drive HSTL signals throughout the circuit backplane or convert the Positive Emitter-Coupled Logic (PECL) based timing signal from a master Phase Lock Loop (PLL) clock generator to an HSTL-based configuration for distributing nine separate clock signals.
