CY2XF34FLXCT

Programmable Timers And Oscillators Overview

The CY2XF34FLXCT is a field-programmable high-performance LVPECL oscillator manufactured by Cypress Semiconductor. It integrates a low-noise PLL and an internal crystal to generate output frequencies between 50 MHz and 690 MHz. The device features two frequency margining control pins (FS0, FS1) for selecting among four factory-configured or user-defined frequencies. It operates on a 3.3 V supply (3.135–3.465 V) or a 2.5 V supply (2.375–2.625 V). Typical RMS phase jitter is less than 1 ps at 106.25 MHz. The component is housed in a 6-pin ceramic LCC package measuring 5.0 × 3.2 mm.

Programmable Timers And Oscillators Feature Summary

• Differential LVPECL output with typical RMS phase jitter under 1 ps
• Frequency margining via two CMOS input pins (FS0, FS1)
• Output frequency range from 50 MHz to 690 MHz
• Field-programmable One Time Programmable (OTP) architecture

Programmable Timers And Oscillators Applications

• System manufacturing test and product development margin testing
• High-frequency clock generation for digital systems
• Applications requiring low-jitter differential clock signals

Programmable Timers And Oscillators Procurement Notes

Verify the specific programming configuration required for the application before ordering, as this is a field-programmable device. Confirm that the commercial temperature range (0 °C to 70 °C) meets system requirements. Ensure the design supports the necessary JEDEC programming file generation using CyberClocks Online Software.

Programmable Timers And Oscillators Selection Notes

Select this part when pin-controlled frequency margining is required. Note that the device cannot generate frequencies in the ranges of 521 MHz to 529 MHz and 596 MHz to 617 MHz. Industrial variants are available if operation below 0 °C is needed. Verify termination circuit compatibility with the chosen supply voltage (VDD-2V for 3.3V or VDD-1.5V/VDD-2V for 2.5V).

Programmable Timers And Oscillators Part Context

The CY2XF34FLXCT belongs to the CY2XF34 family of high-performance oscillators. The 'F' suffix indicates it is field-programmable, while 'LXC' denotes the 6-pin ceramic LCC package. The 'T' suffix specifies tape and reel packaging. This distinguishes it from factory-configured versions which do not require external programming.

Programmable Timers And Oscillators Replacement Considerations

The datasheet lists the CY2XF34FLXIT as an industrial temperature variant of the same field-programmable device. No other direct cross-model substitutes are documented in the provided text.
