The 1:1 input-to-output ratio and differential output (LVPECL) make it a clean fit for a point-to-point clock tree where a low-jitter, high-frequency reference is needed for a single destination — a SerDes reference clock, an FPGA transceiver input, or a high-speed ADC sampling clock. Not rated for industrial or automotive thermal profiles. The 0.65 mm pin pitch is two-layer-board friendly — the LVPECL output pair (Q, Q#) routes as a controlled-impedance differential pair with a ground plane underneath. The crystal input pins (XI, XO) should be kept short and isolated from the output traces to avoid coupling the output edge back into the oscillator.","metaTitle":"Infineon CY2XP21ZXC Clock Generator, 140MHz, PLL, 8-TSSOP","metaDescription":"Infineon CY2XP21ZXC clock generator IC with integrated PLL, 140MHz max frequency, LVPECL output, 8-TSSOP package.
