DESCRIPTION
The PL611s-18 is a low-cost general purpose
frequency synthesizer and a member of PhaseLink’s
PicoPLL family, the worlds smallest programmable
clocks. PhaseLink’s PL611s-18 offers the versatility
of using a single Crystal (MHz) or Reference Clock
input and producing up to two (kHz/MHz) system
clocks, or a combination of Reference and low
frequency outputs. The PL611s-18 is designed for
low-power applications with very stringent space
requirements and consumes ~1.0mA, while
producing 2 distinct outputs of 27MHz and 32kHz.
The power down feature of PL611s-18, when
activated, allows the IC to consume less than 5µA of
power.
The PL611s-18 fits in a small DFN, SC70, or SOT23
package. Cascading of the PL611s-18 with other
PhaseLink programmable clocks allow generating
system level clocking requirements, thereby
reducing the overall system implementation cost.
In addition, one programmable I/O pin can be
configured as Output Enable (OE), Frequency
switching (FSEL), Power Down (PDB) input, or CLK1
(CLK0, FREF, FREF/2) output.
