Description
The Si5356B 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 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.
