Overview

Description

CY2305CSXI-1HT is a Cypress (now part of Infineon) clock-management device: an I2C-programmable clock generator and fan-out buffer. It takes a single reference clock and provides multiple output clocks whose frequencies are programmable via I2C, making it ideal for distributing system clocks to processors, FPGAs/ASICs, and serial interfaces.
Key points:
- I2C control interface for programming and power-down/enable of outputs.
- Multi-output clock distribution with programmable drive strength.
- Compatible with crystal or external oscillator references; designed for low jitter and low power.
- Industrial temperature variant (-40°C to 85°C) in an SXI package.
Typical uses:
- CPU/SoC, FPGA, and peripheral clock generation.
- Video, memory, PCIe/USB/Ethernet clocking, and other high-speed digital systems.
In short: CY2305CSXI-1HT is a compact, I2C-programmable clock source and distributor, ideal for flexible, low-jitter clocking in mixed-signal boards.
