CY2V014FLXCT

Overview

The CY2V014FLXCT is a field-programmable LVPECL Voltage Controlled Crystal Oscillator (VCXO) manufactured by Cypress Semiconductor. It integrates a low-noise PLL and an embedded crystal to generate output frequencies ranging from 50 MHz to 690 MHz. The device operates on a single supply voltage of either 3.3 V or 2.5 V and features a typical RMS phase jitter of 1 ps. Frequency adjustment is achieved via an analog control voltage applied to the VIN pin, allowing for precise tuning within the specified pull range.

Feature Summary

• Field-programmable architecture allows custom frequency configuration using CyberClocks Online Software
• Integrated low-noise PLL with embedded crystal eliminates external components
• LVPECL differential outputs with 1 ps typical RMS phase jitter
• Configurable OE/PD# pin supports fast Output Enable or Power-down modes

Applications

• Hard disk drive (HDD) clocking systems
• Consumer electronics requiring low-jitter timing
• Networking equipment synchronization

Procurement Notes

Verify that the specific part number matches the required temperature range and programming status. The 'F' suffix indicates a field-programmable device that requires customer-side programming before use. Confirm the package type is the 6-pin ceramic LCC in tape and reel format. Contact the manufacturer for factory-configured alternatives if programming capabilities are unavailable.

Selection Notes

Select this component when a programmable VCXO with LVPECL outputs is required. Ensure the design accommodates the analog VIN control voltage for frequency pulling. Verify power supply compatibility with either 2.5 V or 3.3 V rails. Consider the 10 ms start-up time if rapid wake-up from power-down mode is necessary.

Part Context

This part belongs to the CY2V014 family of high-frequency VCXOs. The FLXCT designation specifically identifies the field-programmable variant in a commercial temperature range (0°C to 70°C) packaged in a 6-pin ceramic LCC SMD. Other variants include factory-configured models and industrial temperature options.

Replacement Considerations

Direct replacements must match the LVPECL output standard, 6-pin LCC package, and VCXO functionality. Field-programmable equivalents from other manufacturers may require software adaptation. Factory-configured parts like CY2V014LXCxxxT offer fixed frequencies but lack reprogrammability.
