XL Family of Low Phase Noise
Quartz-based PLL Oscillators
Datasheet
XL
Description
The IDT XL devices (XO and VCXO options) 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 XL series crystal oscillators utilize a
family of proprietary ASICs, with a key focus on noise reduction
technologies.
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 XL devices
are an excellent choice over the conventional technologies. The
XL (XO option) devices have stabilities as tight as ±20ppm and
the XL (VCXO option) devices have ±50ppm APR. Either option
provides extremely quick delivery for both standard and custom
frequencies.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the device. 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.
