DESCRIPTION
The PLL502-22 is a monolithic low jitter and low
phase noise (-130dBc/Hz @ 10kHz offset) VCXO IC
with LVDS output, for 384MHz to 768MHz output
range. It allows the control of the output frequency
with an input voltage (VIN), using a low cost crystal.
The chip provides a pullable output at a frequency of
F
XIN
x 32. This makes the PLL502-22 ideal for a wide
range of applications, including 622.08MHz for
SONET.
