XU Family of Low Phase Noise

Quartz-based PLL Oscillators

Datasheet

Description

Features

▪ Frequency range: 0.016MHz to 1500MHz^[1]

The XU devices are low phase noise quartz-based PLL oscillators

supporting a large range of frequencies and output interface

types. These devices are designed to operate at three different

power supplies and are available in multiple package sizes as well

as temperature grades.

▪ Output types: LVDS, LVPECL, HCSL, LVCMOS

▪ Supply voltage options: 1.8V, 2.5V, or 3.3V

▪ Phase jitter (1.875MHz to 20MHz): 100fs typical

▪ Phase jitter (12kHz to 20MHz): 300fs typical

▪ Package options:

With a patented one-time program (OTP) allowing for infinite

memory shelf life, the XU devices can be programmed to generate

an output frequency from 16kHz to 1500MHz with a resolution as

low as 1Hz accuracy. The configuration capability of this family of

devices allows for fast delivery times for both sample and large

production orders.

• 5.0 × 3.2 × 1.2 mm

• 7.0 × 5.0 × 1.3 mm

▪ Operating temperature: -20°C to +70°C

• Frequency stability options: ±20, ±25, ±50, or ±100 ppm

▪ Operating temperature: -40°C to +85°C

• Frequency stability options: ±25, ±50, or ±100 ppm

▪ Operating temperature: -40°C to +105°C

• Frequency stability options: ±50 or ±100 ppm

Pin Assignments

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

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

[a] Pulled high internally = output enabled.

[b] Low = output disabled.

[c] Do not connect for LVCMOS. For XLVCMOS both OUT and OUT2

are ON and in opposite phase.

See Ordering Information for more details.

[1] There is a dead zone between 1037.5MHz to 1300MHz.

Contact support for frequencies above 1300MHz.
