The Cypress CY2XL12ZXI02 is a single-circuit clock generator built around an internal PLL. It accepts a CMOS or crystal reference on the input side and delivers a differential LVDS output at up to 100 MHz. The 1:1 input-to-output ratio means it is a clean frequency-synthesis and signal-type translation block — not a fanout buffer. Typical deployment is on a SERDES reference clock tree, FPGA transceiver bank, or any board where a single-ended oscillator needs converting to a low-jitter differential clock for downstream PLLs or high-speed logic.
Supply voltage and temperature — the operating envelope
The part runs from a 2.375 V to 2.625 V supply or a 3.135 V to 3.465 V supply.
Package and mounting — board-level fit
Housed in an 8-lead TSSOP (4.40 mm width), surface-mount. The 8-TSSOP footprint is common across many Cypress clock parts, so a board layout for a sibling often accepts this device with no change. No special thermal management is needed at the 100 MHz output rate.
Franchised distribution carries it, and independent channels hold spot inventory for quick-turn needs.
