Shenzhen Mingjiada Electronics Co., Ltd, as a well-known electronic components distributor in China, supplies Skyworks SI53307-B-GMR ultra-low additional jitter fan-out clock buffer in stock, providing accurate clock solutions for all kinds of high-frequency applications.

Product Description Of SI53307-B-GMR

SI53307-B-GMR is a universal 2 : 2 low jitter clock buffer/level translator with a pin-selectable output clock signal format and divider selection. The SI53307-B-GMR features a glitchless switching mux, making it ideal for redundant clocking applications. The SI53307-B-GMR utilizes advanced CMOS technology to fanout 2 from 1 to 725 MHz with guaranteed low additive jitter, low skew, and low propagation delay variability. The SI53307-B-GMR 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.

SI53307-B-GMR up to 10 Universal Outputs from Any-Format Input and Wide Frequency Range from 1MHz to 725MHz.

SI53307-B-GMR feature typical ultra-low jitter characteristics of 50 fs and operate over a wide frequency range. Built-in LDOs deliver high PSRR performance and reduce the need for external components, simplifying low-jitter clock distribution in noisy environments.
