Si53340-B-GM LVDS Low Jitter Clock Buffer

The Si53340-B-GM is a LVDS 2 : 4 low jitter clock buffer. The Si53340-B-GM features a glitchless switching mux, making it ideal for redundant clocking applications. The device utilizes our advanced CMOS technology to fanout 4 clocks from DC  to 1250 MHz with guaranteed low additive jitter, low skew and low propagation delay variability. The Si53340-B-GM 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.
