CY2304SXI-1T

The Infineon Technologies CY2304SXI-1T is a 3.3V Zero Delay Buffer, part of the CY2304 family, designed to distribute high-speed clocks in performance-critical applications like PCs, workstations, datacom, and telecom systems.

This buffer utilizes an on-chip Phase-Locked Loop (PLL) to lock onto an input clock signal. It offers zero input-to-output propagation delay, adjustable by capacitive load on the FBK input. The device provides multiple low-skew outputs, with input-to-output skew guaranteed to be less than 250 ps and output-to-output skew less than 200 ps. It operates within a frequency range of 10 MHz to 133 MHz and exhibits a typical peak cycle-to-cycle jitter of 90 ps at 66 MHz with a 15 pF load.

The CY2304SXI-1T is housed in a space-saving 8-pin SOIC package with a 0.154" (3.90mm) width. It supports a voltage range of 3V to 3.6V and operates across an industrial temperature range of -40°C to 85°C. The device enters a power-down state with less than 25 μA current draw when no rising edges are detected on the REF input, tri-stating all outputs and turning off the PLL.

Available in multiple configurations, the CY2304-1 variant ensures output frequencies equal the reference frequency. The CY2304-2 variant allows for Ref, 1/2x, or 2x frequencies on each output bank, depending on which output drives the feedback pin. This part is suitable for surface mount applications.
