Overview

The SY89202UMG is a precision, high-speed, integrated clock divider LVPECL fanout buffer capable of handling clocks up to 1.5GHz. Optimized for communications applications, the three independently controlled output banks are phase matched and can be configured for pass-through (÷1), ÷2 or ÷4 divide ratios.The differential input includes Micrel's unique, 3-pin input termination architecture that allows the user to interface to any AC- or DC-coupled signal as small as 100mV (200mVpp) without any level shifting or termination resistor networks in the signal path. The low skew, low jitter outputs are 800mV, 100k compatible LVPECL, with extremely fast rise/fall times guaranteed to be less than 220ps.The EN (enable) input guarantees that the ÷1, ÷2 and ÷4 outputs will start from the same state without any runt pulse after an asynchronous MR (master reset) is asserted. This is accomplished by enabling the outputs after a four-clock delay to allow the counters to synchronize.The SY89202UMG is part of Micrel's Precision Edge® product family.
