DESCRIPTION
The PLL602-89 is a high performance multiple output XO IC chip. It provides 1 pair of LVDS and 1 CMOS outputs.
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.
