SY89230U Description
The SY89230U is a precision, low jitter 3.2 GHz ÷3, ÷5 clock divider with an LVPECL output. The differential input includes Micrel’s unique, 3-pin internal termination architecture that allows the input to interface to any differential signal (AC- or DCcoupled) as small as 100mV (200mVPP) without any level shifting or termination resistor networks in the signal path. The outputs are 800mV, 100Kpatible LVPECL with...
