XK23L156L312L625I

XK23L156L312L625I is a XK series ultra-low phase noise quartz-based PLL oscillator. It is a second-generation follow-on to the XF ProXO high-performance oscillator. The device is often referred to as ProXO II. It uses internal regulators to provide excellent PSNR characteristics. The device is offered in a range of industry standard package footprints. The device can be factory programmed with up to three frequencies and/or output types that are selected by the 3-level FS pin. Typical applications are 10G to 800G Ethernet, 100G to 400G OTN, 3G to 24G SDI broadcast video, servers, switches, storage, accelerators, NICs, HBAs.
