SILICON LABS SI5356A-B-GM

The Si5356 is a highly flexible, I²C-programmable clock generator capable of synthesizing four completely non-integer-related frequencies up to 200 MHz. The device features four output banks, each supporting two CMOS outputs at identical frequencies. Using a patented fractional divider technology, all outputs are guaranteed 0 ppm frequency synthesis error regardless of configuration, enabling a single device to replace multiple clock ICs and crystal oscillators. Each output bank is independently configurable, supporting 1.8, 2.5, or 3.3 V. The device is programmable via an I²C/SMBus-compatible serial interface and supports 1.8, 2.5, or 3.3 V core supply voltages.
