CY2X013FLXIT

Programmable Timers And Oscillators Overview

The CY2X013FLXIT is a field-programmable LVDS crystal oscillator manufactured by Cypress Semiconductor. It utilizes an integrated low-noise phase-locked loop (PLL) to synthesize output frequencies ranging from 50 MHz to 690 MHz, excluding specific gaps between 521–529 MHz and 596–617 MHz. The device features less than 1 ps typical RMS phase jitter and operates on a 3.3 V or 2.5 V supply. It provides a differential LVDS clock output pair and includes an asynchronous output enable or power-down function via Pin 1. The component is housed in a 6-pin leadless chip carrier (LCC) package with dimensions of 5.0 × 3.2 mm.

Programmable Timers And Oscillators Feature Summary

• Field-programmable architecture allowing custom frequency configuration via CyClockWizard software

Programmable Timers And Oscillators Applications

• High-performance system clocking requiring low jitter
• Communications equipment timing
• Consumer electronics requiring programmable clock sources
• Industrial applications needing industrial temperature range operation (-40°C to 85°C)

Programmable Timers And Oscillators Procurement Notes

Verify the 'F' suffix in the part number confirms the device is field-programmable and requires external programming before installation. Confirm the 'I' suffix indicates the industrial temperature grade (-40°C to 85°C). Ensure the ordering suffix 'T' corresponds to tape and reel packaging. Cross-reference the required output frequency against the specified non-continuous ranges to ensure compatibility.

Programmable Timers And Oscillators Selection Notes

Select this component when a customizable clock source is needed rather than a fixed factory-configured unit. Consider the 5 ms startup time if rapid wake-up from power-down is critical. Evaluate the need for industrial temperature stability versus commercial grades, as internal crystals differ. Ensure the design supports the required JEDEC programming file generation and compatible programmer hardware.

Programmable Timers And Oscillators Part Context

The CY2X013 series includes both factory-configured variants (e.g., CY2X013LXI125T) and field-programmable versions. The FLXIT designation specifically identifies the field-programmable variant in the industrial temperature range packaged in tape and reel. This distinguishes it from the LXCxxxT commercial grade parts and the pre-programmed LXIxxxT industrial parts.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the 6-pin ceramic LCC package and LVDS output requirements. Field-programmable equivalents may require reprogramming with appropriate software tools. Fixed-frequency substitutes like the CY2X013LXI125T offer immediate usability but lack frequency customization capabilities.

Programmable Timers And Oscillators FAQ

What is the difference between the OE and PD# functions on Pin 1?

Pin 1 can be programmed as either Output Enable (OE) or Power-Down (PD#). OE allows quick asynchronous enabling/disabling of the clock output without reducing core power consumption. PD# puts the device into a low-power state, but requires longer wake-up time as the PLL must reacquire lock.

Are there any frequency gaps in the CY2X013's output range?

Yes, while the general range is 50 MHz to 690 MHz, the device cannot generate frequencies in the ranges of 521 MHz to 529 MHz and 596 MHz to 617 MHz.

How is the CY2X013FLXIT programmed?

It is programmed using CyClockWizard™ software to generate a JEDEC (.jed) file. Programming requires a CyClockMaker Clock Programmer Kit (CY3675-CLKMAKER1) with a CY3675-LCC6A socket adapter.
