CY2308ESXI-4

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2308ESXI-4 is a zero-delay buffer manufactured by Cypress Semiconductor Corp. It operates at 3.3 V and accepts one reference input to drive multiple low-skew outputs. The device features an on-chip phase-locked loop (PLL) that locks to the input clock, ensuring zero input-to-output propagation delay adjustable by capacitive load on the feedback input. It supports operating frequencies from 10 MHz to 133 MHz with typical cycle-to-cycle jitter of 75 ps at 66 MHz and 15 pF load. The component is housed in a space-saving 16-pin package.
