IDT XO LVPECL Crystal Oscillator
XUQ
DATASHEET
Description
Features
The XUQ is an Ultra Precision LVPECL crystal oscillator with
300fs typical phase jitter over 12kHz to 20MHz bandwidth.
Available in a wide frequency range from 16kHz to 670MHz,
the IDT XUQ series crystal oscillator utilizes a family of
proprietary ASICs, with a key focus on noise reduction
technologies.
• Frequency range: 0.016 to 670MHz
• Output type: LVPECL
• Frequency stability: ±20ppm, ±25ppm, ±50ppm, or
±100ppm
• Supply voltage: 1.8V, 2.5V, or 3.3V
• Phase jitter (1.875MHz to 20MHz): 100fs typical
• Phase jitter (12kHz to 20MHz): 300fs typical
The 4th 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 XUQ is
an excellent choice over the conventional technologies. The
XUQ has stabilities as tight as ±20ppm with extremely quick
delivery for both standard and custom frequencies.
• Package options: 5.0mm x 3.2mm x 1.2mm (JS6)
7.0mm x 5.0mm x 1.3mm (JU6)
• Operating temperatures: -20°C to +70°C or -40°C to +85°C
