CY2XF34

CY2XF34 High Performance LVPECL Oscillator with Frequency Margining – Pin Control High Performance LVPECL Oscillator with Frequency Margining - Pin Control Features ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Functional Description The CY2XF34 is a high performance and high frequency Crystal Oscillator (XO). It uses a Cypress proprietary low noise PLL to synthesize the frequency from an integrated crystal. The output frequency can be changed through two select pins, allowing easy frequency margin testing in applications. The CY2XF34 is available as a factory configured device or as a field programmable device. Low Jitter Crystal Oscillator (XO) Less than 1 ps Typical RMS Phase Jitter Differential LVPECL Output Output Frequency from 50 MHz to 690 MHz Two Frequency Margining Control Pins (FS0, FS1) Factory Configured or Field Programmable Integrated Phase-Locked Loop (PLL) Supply Voltage: 3.3 V or 2.5 V Pb-Free Package: 5.0 × 3.2 mm LCC Commercial and Industrial Temperature Ranges Logic Block Diagram 4 CRYSTAL OSCILLATOR LOW-NOISE PLL OUTPUT DIVIDER 5 FS1 1 FREQUENCY SELECT DECODE CLK CLK# FS0 2 Pinouts Figure 1.
