CY2XF24LXI625T

Programmable Timers And Oscillators Overview

The CY2XF24LXI625T is a factory-configured high-performance LVPECL oscillator manufactured by Cypress Semiconductor. It operates within an output frequency range of 50 MHz to 690 MHz and utilizes an integrated low-noise PLL with an internal crystal reference. The device supports frequency margining via an I2C serial interface, allowing selection among four pre-programmed frequencies: 78.125 MHz, 156.25 MHz, 312.50 MHz, and 625.00 MHz (default). It features typical RMS phase jitter ranging from 0.29 ps to 0.37 ps across these frequencies. The component is housed in a 6-pin ceramic leadless chip carrier (LCC) package and supports both 2.5 V and 3.3 V supply voltages.

Programmable Timers And Oscillators Feature Summary

• Differential LVPECL output with typical RMS phase jitter between 0.29 ps and 0.37 ps
• I2C-controlled frequency margining supporting four selectable output frequencies
• Integrated low-noise PLL synthesizing frequency from an internal crystal
• Factory-configured for industrial temperature range (-40 °C to 85 °C)

Programmable Timers And Oscillators Applications

• Frequency margin testing during product development or in-system manufacturing
• High-speed digital systems requiring low-jitter clock signals
• Applications utilizing the I2C bus for dynamic clock configuration

Programmable Timers And Oscillators Procurement Notes

Verify that the specific part number corresponds to the factory-configured variant rather than the field-programmable version. Confirm the required operating temperature range matches the 'I' suffix designation for industrial specifications. Ensure the ordering suffix indicates tape and reel packaging if automated assembly is intended.

Programmable Timers And Oscillators Selection Notes

Select this component when a fixed set of four LVPECL frequencies is sufficient for the design requirements. The default output frequency is 625.00 MHz. If custom frequencies outside the standard configurations are needed, consider the field-programmable CY2XF24FLX variants instead. Verify that the system power supply can accommodate either 2.5 V or 3.3 V operation.

Programmable Timers And Oscillators Part Context

This device belongs to the CY2XF24 family of high-performance LVPECL oscillators. The 'LXI' suffix denotes a factory-configured unit designed for the industrial temperature range (-40 °C to 85 °C), distinguishing it from commercial versions or field-programmable models.
