DESCRIPTION

The PL133-37 is an advanced fanout buffer design

for high performance, low-power, small form-factor

applications. The PL133-37 accepts a reference

clock input of 1MHz to 150MHz and produces three

outputs of the same frequency. Reference clock in-

puts may be LVCMOS or sine-wave signals (the in-

puts are internally AC-coupled). Offered in a small

3mm x 3mm SOT23, the PL133-37 offers the best

phase noise and jitter performance and lowest power

consumption of any comparable IC.
