The part handles clock frequencies up to 250 MHz and operates from a 3.135 V to 3.465 V supply rail. The 1:20 ratio means a single clock source fans out to twenty independent HCSL lanes, each capable of driving a 50-ohm terminated transmission line — typical for PCIe reference clocks, SerDes reference distribution, or multi-card backplane timing. The differential input and output paths (Yes/Yes) maintain signal integrity across the fanout tree. ## Ultra-low additive jitter and temperature range The device is described as a buffer with ultra-low additive jitter, which matters when distributing a clean clock to multiple receivers — additive jitter is the noise the buffer itself injects, not the input clock's phase noise. For a 250 MHz reference clock, keeping additive jitter in the sub-picosecond range preserves the timing margin for high-speed serial links. ## 72-QFN package and board integration The 72-VFQFN Exposed Pad (10x10 mm body,) provides a central thermal pad for heat sinking to the PCB ground plane. The exposed paddle must be soldered to a copper pour with sufficient vias to the inner layers — without a low-thermal-resistance path, the junction temperature rises above the 85°C ambient limit, especially when all twenty outputs are switching at 250 MHz. The tape-and-reel packaging supports automated pick-and-place; cut-tape samples are also available for prototyping. No pin-compatible second source is recorded — the fanout ratio and HCSL output type are specific to this Microchip device.","metaTitle":"Microchip ZL40292LDF1 Fanout Buffer, 1:20, 250 MHz, 72-QFN","metaDescription":"Microchip ZL40292LDF1 fanout buffer (distribution), 1:20 ratio, 250 MHz max, HCSL output, differential IO, -40 to 85°C.
