Product Overview
The Si535/536 is an ultra-low jitter crystal oscillator (XO) from Skyworks Solutions, Inc., utilizing advanced DSPLL circuitry. It offers a wide range of output frequencies from a single fixed crystal, providing exceptional frequency stability and reliability. Its IC-based design and DSPLL clock synthesis ensure superior supply noise rejection, making it ideal for generating low-jitter clocks in noisy communication system environments. The device is factory programmed, reducing lead times associated with custom oscillators. Available in a 5 x 7 mm package with LVPECL and LVDS output options, and 3.3/2.5 V supply options.
