CY27410LTXI-013T

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY27410LTXI-013T is a 4-PLL spread-spectrum clock generator in a 48-pin QFN package. It supports crystal inputs from 8 MHz to 48 MHz and reference clocks up to 700 MHz differentially. Outputs range from 3 MHz to 700 MHz, supporting LVDS, LVPECL, HCSL, CML, and LVCMOS logic levels. The device features four fractional N-type PLLs with VCXO capability (±120 ppm) and spread-spectrum modulation (0.1% to 5%). It provides up to 12 outputs split into two banks, with a maximum RMS phase jitter of 1 ps at 12-kHz to 20-MHz offset. Operating voltage ranges from 1.71 V to 3.46 V across 1.8 V, 2.5 V, and 3.3 V supplies.
