Microchip's MX85 family of parts are ultra-low phase noise clocking solutions that integrate the crystal, synthesizer, and fanout buffers, providing up to two frequencies from a single 5mm × 7mm LGA package.  Integrating the entire clock chain means that 162fs jitter performance includes fanout and crosstalk. The MX85 family offers a series of crystal frequency options that generate commonly-required Ethernet, storage, telecommunications, and computing clock frequencies up to 840MHz. Configuring the MX85 parts using OTP options, a variety of output frequencies are available.  Optimized for applications that require performance, reliability, and high integration, the MX85 family delivers the complete clocking chain from crystal to fanout buffer.
