DESCRIPTION
The PL611s-19 is a low-cost general purpose
frequency synthesizer and a member of PhaseLink’s
Factory Programmable ‘Quick Turn Clock (QTC)’
family. PhaseLink’s PL611s-19 offers the versatility
of using a single Reference Clock input and
producing up to two (kHz or MHz) system clock
outputs. Designed for low-power applications with
very stringent space requirement, PL611s-19
consumes <1.0mA, while producing 2 distinct
outputs of 27MHz and 32kHz. The power down
feature of PL611s-19, when activated, allows the IC
to consume less than 5µA of power.
PL611s-19 fits in a small DFN, SC70, or SOT23
package. Cascading of the PL611s-19 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 Power Down (PDB) input, Output
Enable (OE), or Frequency switching (FSEL). CLK1
can be programmed as (CLK0, FREF, FREF /2) output.

I Reference input pin
This programmable I/O pin can be configured as an Output Enable (OE)
input, Power Down input (PDB) or On-the-Fly Frequency Switching
Selector (FSEL). This pin has an internal 60KΩ pull up resistor for OE,
O PDB & FSEL.
The OE and PDB features can be programmed to allow the output to float
(Hi Z), or to operate in the ‘Active low’ mode.
