XL Family of Low Phase Noise

Quartz-based PLL Oscillators

Datasheet

Description

The IDT 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 V

(Pin 6) and GND (Pin 3) on 6-pin

devices, or V

(Pin 4) and GND (Pin 2) on 4-pin devices.
