SILICON LABS SI5356A-B04356-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 has four banks of outputs with each bank supporting two CMOS outputs at the same frequency. Using Silicon Laboratories' patented MultiSynth fractional divider technology, all outputs are guaranteed to have 0 ppm frequency synthesis error regardless of configuration, enabling the replacement of multiple clock ICs and crystal oscillators with a single device. Each output bank is independently configurable to support 1.8, 2.5, or 3.3 V. The device is programmable via an I²C/SMBus-compatible serial interface and supports operation from a 1.8, 2.5, or 3.3 V core supply.
