The PRL21X is a SingleDie™ SAW MEMS-based low-noise programmable any-rate family of XOs and VCXOs. It leverages the intrinsic advantages of a monolithic MEMS technology, where the SAW MEMS resonator and CMOS circuitry are both implemented on the same die. This innovative approach offers zero thermal latency and high resistance to shock and vibration, making it an ideal candidate for industrial and automotive applications with an extended operating temperature range of $-40 ^oC to $+125 ^o.

The PRL21X features a programmable frequency range from 1 to 1000 MHz. It supports XO, VCXO, and DCXO modes, as well as Single, Dual, Quad, and Any-Rate (I2C) configurations. The device exhibits low phase noise with a typical integrated RMS Jitter of 350 fs for any frequency up to 1 GHz.

The PRL21X family offers a high degree of programmability, allowing customers to generate a wide variety of part numbers through a structured ordering guide. Users can select from various product types, including single, dual, quad, or any-rate XO and VCXO variants. Output formats are also customizable, with options such as CMOS, LVDS, LVPECL, CML, and HCSL.

The ordering guide also allows for the specification of different supply voltages (3.3V, 2.5V, 1.8V) with an auto-detect option. You can also define the package type, choosing between plastic, ceramic, or a Chiplet die form. This flexibility ensures the PRL21X can be precisely configured to meet the specific requirements of a vast range of applications, from networking to industrial and automotive systems.
