Description

The Renesas XL devices (XO and VCXO options) are

ultra-precision crystal oscillators with 750 to 890fs typical phase

jitter over 12kHz to 20MHz bandwidth. Available in a wide

frequency range from 0.750MHz to 1350MHz, the XL series

crystal oscillators utilize a family of proprietary ASICs, with a key

focus on noise reduction technologies.

The 3rd order Delta Sigma Modulator reduces noise to the levels

that are comparable to traditional Bulk Quartz and SAW

oscillators. With short lead-time, low cost, low noise, wide

frequency range, excellent ambient performance, the XL devices

are an excellent choice over the conventional technologies. The

XL (XO option) devices have stabilities as tight as ±20ppm and

the XL (VCXO option) devices have ±50ppm APR. Either option

provides extremely quick delivery for both standard and custom

frequencies.

Pin Assignments

(XO Option)

NOTE: To minimize power supply line noise, a 0.01μF bypass

capacitor should be placed between VDD (Pin 6) and GND (Pin 3).

(VCXO Option)

NOTE: To minimize power supply line noise, a 0.01μF bypass

capacitor should be placed between VDD (Pin 6) and GND (Pin 3).
