Si53352A-01AM 1:2 Clock Buffer Level/Translat

The Si53352A-01AM is a universal 1 : 2 low jitter clock buffer/level translator. Users can fully customize the input/output format and voltages using ClockBuilder Pro, or choose the fixed-function alternative that features hardware input pins to select the input/output clock format level (LVDS, LVPECL, HCSL, LVCMOS). The Si53352A-01AM utilizes Skyworks' advanced CMOS technology to fanout ten copies of a 10 to 333.33 MHz input reference clock, with guaranteed low additive jitter, low skew and low propagation delay variability. The Si53352A-01AM features minimal cross-talk and provides superior supply noise rejection, simplifying low jitter clock distribution in noisy environments. Independent core and output bank supply pins provide integrated level translation without the need for external circuitry.

ClockBuilder Pro Field Programmer

When used with ClockBuilder Pro software, the ClockBuilder Pro Field Programmer makes it simple for systems designers to develop, program, and debug any Si5332/8, Si5350/1/6/7, Si534x/6x/8x/9x, Si540x, and Si55xx part families clock device “in-system,” or in one of the convenient QFN sockets. The field programmer supports I2C or SPI interfaces to the host system, and SPI to the field programmer's QFN socket boards.
