The 2.7 GHz maximum frequency covers the full range of 10G Ethernet reference clocks, FPGA transceiver reference oscillators, and SERDES PLL distribution. Differential input and output paths (Yes/Yes per the spec) reject common-mode noise coupled onto the clock traces between the source and the buffer, which is the dominant jitter mechanism on densely routed boards above 1 GHz. ## Supply range and signal compatibility Inputs accept ECL, HSTL, or PECL levels — a single device bridges between a PECL oscillator and an ECL-terminated fanout tree. Outputs are ECL or PECL, which require external termination resistors (typically Thevenin to VCC-2 V) rather than the series-source termination used for LVCMOS. The 32-LQFP (7x7 mm) package keeps the trace length from the output pin to the termination pair short enough to avoid stub reflections at 2.7 GHz. ## Temperature grade and lifecycle Note the RoHS compliance status: listed as RoHS non-compliant. This indicates a legacy lead-bearing solder finish (typically SnPb or AuSn). The part is still manufacturable and orderable, but the finish requires a Pb-compatible soldering profile — not a problem for mixed-technology assembly lines that maintain a SnPb reflow zone for legacy BOMs.","metaTitle":"NXP MC100ES6111FAR2 Fanout Buffer, 2:10, 2.7 GHz, 32-LQFP","metaDescription":"NXP MC100ES6111FAR2 active-production 2:10 fanout buffer with 2.7 GHz max frequency, differential I/O, ECL/HSTL/PECL input. 32-LQFP.
