4 -Output, Any Frequency (< 350 MHz), Any Output, Clock Generator Si5335A

Input Frequency Max (MHz)

Output Frequency Max

The Si5335A 4-output differential clock generator is is capable of synthesizing 4 completely non-integer-related frequencies between 1 and 350 MHz. The device has four banks of outputs with each bank supporting one differential pair or two single-ended outputs. Using Silicon Labs' 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.
