Infineon Technologies CY2XF24LXI009T

Overview

CY2XF24LXI009T from Infineon Technologies / Cypress is a high-performance LVPECL crystal oscillator with frequency margining through I²C control. It is designed for applications requiring a low-jitter differential clock, integrated PLL synthesis, configurable output frequency behavior, and a compact 5.0 mm × 3.2 mm leadless chip carrier package.

As an industrial-temperature CY2XF24 configuration, CY2XF24LXI009T supports a 50 MHz to 690 MHz output frequency range, less than 1 ps typical RMS phase jitter, differential LVPECL outputs, 2.5 V or 3.3 V supply operation, and I²C-based frequency margining. For engineers reviewing the CY2XF24LXI009T datasheet, CY2XF24LXI009T pinout, CY2XF24LXI009T application, or CY2XF24LXI009T equivalent, this device is mainly relevant to networking equipment, telecom timing, high-speed FPGA clocks, serializer/deserializer reference clocks, and margin-testable clock trees.

Technical Context

In a clock-distribution design, CY2XF24LXI009T operates as a high-frequency XO using an integrated crystal oscillator and a low-noise PLL. The device generates a differential LVPECL clock pair, making it suitable for receivers that need controlled swing, low jitter, and better noise immunity than single-ended oscillator outputs.

The CY2XF24 family includes I²C control for frequency margining, allowing engineers to shift the output frequency during validation without changing the physical oscillator. This is useful for system timing margin tests, clock tolerance analysis, and production or lab verification of downstream devices.

CY2XF24LXI009T uses a 6-pin leadless chip carrier footprint and uses a 6-SMD no-lead device. Because the output is LVPECL, the board design must include proper differential routing, termination, power filtering, and receiver compatibility checks.

Key Specifications

Pinout & Package

The CY2XF24LXI009T pinout provides I²C control pins, supply and ground pins, and a differential LVPECL clock output pair. PCB layout should treat the CLK and CLK# outputs as a controlled differential pair and should apply the termination method required by the receiving LVPECL input standard.

For PCB design, place local decoupling close to the supply pin, keep I²C traces clear of high-noise switching nodes, and route the differential clock pair with controlled impedance, matched length, and clean reference-plane continuity.

Applications

Equivalent & Alternatives

When evaluating CY2XF24LXI009T equivalent devices, engineers should compare output frequency, LVPECL output format, RMS phase jitter, I²C margining support, supply voltage, package, programmed suffix, and temperature grade.

Compared with fixed LVPECL oscillators, CY2XF24LXI009T is selected when I²C frequency margining and programmable clock behavior are important. A replacement must match the exact output standard and programmed suffix, not only the nominal frequency.

Quality

CY2XF24LXI009T should be sourced as original Infineon / Cypress components through traceable and controlled supply channels. Quality verification procedures may include reel-label inspection, top-mark review, programmed suffix confirmation, package inspection, solderability evaluation, and incoming electrical sampling for oscillator output behavior.

Because this part is a timing device with a programmed suffix, procurement should verify the exact frequency configuration and temperature grade before use.

Availability

CY2XF24LXI009T available at Aetrix Electronics and suitable for LVPECL clock generation, frequency-margin testing, high-speed networking timing, FPGA reference clocks, and industrial timing modules requiring stable component supply and traceable sourcing support.

Supply support may include scheduled delivery planning, programmed-part review, tape-and-reel sourcing, BOM continuity assistance, and long-term availability support for OEM manufacturers, EMS providers, and hardware engineering teams.

For production deployment, confirming output frequency, LVPECL termination, supply voltage, package, programmed suffix, temperature grade, and sourcing continuity helps reduce procurement and design risk.

Manufacturer

Infineon Technologies supplies semiconductor products including power devices, microcontrollers, sensors, security ICs, protection devices, and timing products inherited from Cypress for automotive, industrial, computing, communication, and consumer applications.
