PIN CONFIGURATION

DESCRIPTION
The PL611-01 is a low-cost general purpose frequency synthesizer and a member of PhaseLink's Factory
Programmable `Quick Turn Clock (QTC)' family. PhaseLink's PL611-01 product family offers the versatility of
using a single Crystal or Reference Clock input and producing up to three different system clocks. They can
generate any output frequency up to 200 MHz from fundamental crystal input between 10 MHz - 30 MHz, or a 3rd
overtone crystal of up to 75Mhz, or a Reference clock input of up to 200 MHz. Cascading of the ICs to produce
additional clock frequencies is also supported.
