DESCRIPTION
The PLL602-89T is a high performance multiple output XO IC chip. It provides 3 pairs of LVDS and 1 CMOS out-
puts. The chip combines a crystal oscillator (XO) with a multiple-output buffer. It accepts a low cost fundamental
parallel resonant mode crystal from 12MHz to 27MHz, which is reproduced at the outputs. The very low jitter (2.5
ps RMS period jitter) makes this chip ideal for data and telecommunication applications.
