Microsemi / Microchip ZL402x Clock Fanout Buffers

Microsemi / Microchip ZL402x Clock Fanout Buffers offer six fanout combinations with Low-Voltage Positive Emitter-coupled Logic (LVPECL) or Low-voltage Differential Signaling (LVDS) output types. These clock fanout buffers are categorized into miClock and miSmart variants. The ZL402x clock buffers feature low skew and ultra-low additive jitter for the different frequency ranges. The ZL402x clock buffers combine with miClockSynth™ synthesizers to create a simplified, reliable, and low-cost complete clock tree.

The ZL402x clock buffers are offered in a variety of input and output configurations including LVPECL, LVDS, and High-speed Current-Steering-Logic (HCSL). These clock buffers add a serial port interface and integer dividers on the Low Voltage Complementary Metal Oxide Semiconductor (LVCMOS).

The Microsemi / Microchip ZL402x Clock Fanout Buffers are available in QFN-32, QFN-40, and QFN-48 packages with a -40ºC to +85ºC operating temperature range.
