FEATURES
DESCRIPTION
The PLL502-30 is a monolithic low jitter and low
phase noise (-142dBc/Hz @ 10kHz offset) VCXO IC
Die, with CMOS, LVDS and PECL output, covering
the 750kHz to 800MHz output range. It allows the
control of the output frequency with an input voltage
(VCON), using a low cost crystal.
The same die can be used as a VCXO with output
frequencies ranging from F
thanks to frequency selector pads. This makes the
PLL502-30 ideal as a universal die for applications
ranging from ADSL to SONET.
