PL133-47
Low-Power 2.25V to 3.63V DC to 150MHz 1:4 Fanout Buffer IC FEATURES DESCRIPTION п‚ п‚ п‚ п‚ п‚ п‚ п‚ п‚ п‚ The PL133-47 is an advanced fanout buffer design for
high performance, low-power, small form factor applications. The PL133-47 accepts a reference clock input from
DC to 150MHz and provides 4 outputs of the same frequency. 1:4 LVCMOS output fanout buffer for DC to150MHz
Low Additive Phase Jitter of 60fs RMS
8mA Output Drive Strength
Low power consumption for portable applications
Low input-output delay
Output-Output skew less than 250ps
2.5V to 3.3V, В±10% operation
Operating temperature range from -40В°C to 85В°C
Available in 8-Pin SOP GREEN/RoHS package The PL133-47 is offered in a SOP-8L package and it offers
the best phase noise, additive jitter performance, and lowest power consumption of any comparable IC. BLOCK DIAGRAM AND PACKAGE PINOUT CLK0
