SI5355A-B06159-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5355A-B06159-GM is a highly flexible clock generator synthesizing four non-integer related frequencies up to 200 MHz. It features eight CMOS outputs across four banks, each supporting two outputs at the same frequency. The device guarantees 0 ppm frequency synthesis error for any combination of frequencies using patented MultiSynth technology. It accepts a 25 or 27 MHz crystal or a 5–200 MHz input clock. Key electrical parameters include a core supply voltage (VDD) range of 1.8 V to 3.3 V and separate output buffer supply voltages (VDDO) of 1.8 V, 2.5 V, or 3.3 V per bank. Typical period jitter is 50 ps pk-pk, with phase jitter of 2 ps rms from 12 kHz to 20 MHz. The core supply current is typically 45 mA at 100 MHz on all outputs.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-customized configuration associated with the B06159 suffix via the ClockBuilder utility, as this part number represents a unique pin-controlled profile rather than a generic device. Confirm that the required input reference and output frequency combinations match the programmed specifications in the datasheet ordering information section. Ensure compatibility with the intended control logic levels for the multi-function pins.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when replacing multiple discrete oscillators or PLLs with a single device capable of generating four independent, non-integer related frequencies. It is suitable for applications requiring pin-selectable configurations to replace up to three separate clock ICs. Consider the 4x4 mm 24-QFN package size and industrial temperature range (-40 to +85 °C) for space-constrained designs. Verify that the required output drive strength and supply voltage options align with the mixed-supply capabilities of the four output banks.
