XA Family of Low Phase Noise
Quartz-based PLL Oscillators
XA
Datasheet
Description
Features
▪ Conforms to AEC-Q200
The IDT XA devices 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 XA series crystal oscillators utilize a family of proprietary
ASICs, with a key focus on noise reduction technologies.
▪ Frequency range: 0.750MHz to 1350MHz
▪ Output types: LVDS, LVPECL, LVCMOS
▪ Frequency stability: ±25, ±50, or ±100 ppm
▪ Supply voltage: 2.5V or 3.3V
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 XA devices
are an excellent choice over the conventional technologies. The
XA devices have stabilities as tight as ±25ppm with extremely
quick delivery for both standard and custom frequencies.
▪ Phase jitter (12kHz to 20MHz): 750fs to 890fs typical
▪ Package options:
ꢀ 3.2 × 2.5 × 1.0 mm
ꢀ 5.0 × 3.2 × 1.2 mm
▪ Operating temperature: -40°C to +85°C (Grade 3)
ꢀ Frequency stability options: ±25, ±50, or ±100 ppm
▪ Operating temperature: -40°C to +105°C (Grade 2)
ꢀ 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 VDD (Pin 6) and GND (Pin 3)
on 6-pin devices, or VDD (Pin 4) and GND (Pin 2) on 4-pin
devices.
