DESCRIPTION
The PL611s-28 consumes very low-power while
producing high performance clock outputs of up to
55MHz. Designed for low-power applications with
very stringent space requirement, PL611s-28
consumes about 1.2mA, while producing 2 distinct
outputs of 27MHz and 13.5MHz. Designed to fit in a
small SOT, SC70, or SOT23 package for high
performance applications, the PL611s-28 offers
excellent phase noise and jitter performance. The
power down feature of PL611s-28, when activated,
allows the IC to consume less than 5 A of power,
while its programming flexibility allows generating
any output, using a low-cost crystal or reference
input. In addition, one programmable I/O pin can be
configured as Output Enable (OE), Frequency
switching (FSEL), Power Down (PDB) input, or CLK1
