IDT XO HCMOS Crystal Oscillator
XLH
DATASHEET
General Description
Features
The XLH is an HCMOS Crystal Oscillator with 750fs typical
phase jitter over 12kHz to 20 MHz bandwidth. Available in a
wide frequency range from 0.750MHz to 250MHz, the IDT
XLH Series Crystal Oscillator utilizes a family of proprietary
ASICs, with a key focus on noise reduction technologies.
• Frequency range: 0.750 to 250 MHz
• Output Type: HCMOS/LVCMOS Compatible
• Frequency Stability: ± 20ppm, ± 25ppm, ± 50ppm, or ± 100
ppm
• Supply Voltage: 2.5V or 3.3V
• Phase Jitter (1.875MHz to 20MHz): 225fs typical
• Phase Jitter (12kHz to 20MHz): 750fs typical
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 XLH is
an excellent choice over the conventional technologies. The
XLH has stabilities as tight as ±20ppm with extremely quick
delivery for both standard and custom frequencies
• Package options: 3.2mm x 2.5mm x 1.0mm (JX4)
5.0mm x 3.2mm x 1.2mm (JS4)
7.0mm x 5.0mm x 1.3mm (JU4)
• Operating Temperatures: -20°C to +70°C or -40°C to +85°C
