It accepts one differential input and distributes up to eleven CML clock copies at frequencies up to 4.5 GHz. The 1:11 fanout ratio means a single reference oscillator can feed multiple ADC/DAC clocks, SERDES reference lanes, or FPGA transceiver banks without adding external distribution ICs. The CML output type is the usual choice for high-speed serial links because its constant-current swing keeps jitter low. ## Temperature range and supply rail The supply range is 3.15 V to 3.45 V — a tight window that demands a clean 3.3 V rail with ±5 % regulation. ## Lifecycle and compliance ROHS3 compliant.","metaTitle":"LTC6952IUKG#PBF Clock Generator & Fanout Buffer – 4.5 GHz","metaDescription":"Analog Devices LTC6952IUKG#PBF: PLL-based clock generator with 1:11 CML fanout, 4.5 GHz max frequency, -40°C to 125°C.
