IDT XO HCMOS Crystal Oscillator XLH
DATASHEET
Description Features
The XLH is an HCMOS Crystal Oscillator with 750fs typical Frequency range: 0.750 to 250MHz
phase jitter over 12kHz to 20 MHz bandwidth. Available in a
Output Type: HCMOS/LVCMOS Compatible
wide frequency range from 0.750MHz to 250MHz, the IDT
Frequency Stability: 20ppm, 25ppm, 50ppm, or 100
XLH Series Crystal Oscillator utilizes a family of proprietary
ppm
ASICs, with a key focus on noise reduction technologies.
Supply Voltage: 2.5V or 3.3V
Phase Jitter (1.875MHz to 20MHz): 225fs typical
The 3rd order Delta Sigma Modulator reduces noise to the
Phase Jitter (12kHz to 20MHz): 750fs typical
levels that are comparable to traditional Bulk Quartz and SAW
oscillators. With short lead-time, low cost, low noise, wide Package options: 3.2mm x 2.5mm x 1.0mm (JX4)
frequency range, excellent ambient performance, the XLH is 5.0mm x 3.2mm x 1.2mm (JS4)
an excellent choice over the conventional technologies. The 7.0mm x 5.0mm x 1.3mm (JU4)
XLH has stabilities as tight as 20ppm with extremely quick
Operating Temperatures: -20C to +70C or -40C to +85C

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the XLH. These ratings, which are standard values for
IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above
those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions
for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating
temperature range.
