    FEATURES DESCRIPTION п‚ п‚ п‚ п‚ The PL123E-09 (-09H for High Drive) is a high performance, low skew, low jitter zero delay buffer d esigned
    to distribute high speed clocks. It has two low-skew
    output banks, of 4 outputs each, that are synchronized
    with the input. Control of the two banks o f outputs is
    achieved by using the S1 and S2 inputs as shown in
    the Selector Definition table on page 2. п‚ п‚ Frequency Range 10MHz to 220MHz
    Zero input -output delay.
    Low Output to Output Skew
    Optional Drive Strength:
    Standard (8mA) PL123E-09
    High (12mA) PL123E-09H
    2.5V or 3.3V, В±10% operation.
    Available in 16-Pin SOP or TSSOP packages The synchronization is established via CLKOUT feed
    back to the input of the PLL. Since the skew between
    the input and output is less than п‚±100ps, the device
    acts as a zero delay buffer. The input output propagation delay can be advanced or delayed by adjusting the
    load on the CLKOUT pin.
    These parts are not intended for 5V input-tolerant applications. BLOCK DIAGRAM PLL REF Mux CLKOUT CLKA2
