Description
The PI6CX230B is a 3.3V ±5% VCXO and low phase noise 8x
PLL clock generator available in discrete IC form with external
SaRonix crystal. The PI6CX230B features a low-noise 8x clock
multiplication circuit with improved phase noise performance and
LVCMOS output clock signal. The device accepts an external
analog control voltage signal that pulls the output frequency
by ±150 ppM. Contact Pericom/SaRonix for recommended
crystal specifications. For applications that require LVDS output
compatibility, see the PI6CX231A/B.
