Detailed Description
The devices consist of a fundamental-mode, AT-cut
crystal and a synthesizer IC that can synthesize any
one of these frequencies: 77.76MHz, 125MHz,
150MHz, 155.52MHz, 156.25MHz, 160MHz, 250MHz,
300MHz, 311.04MHz, 312.5MHz, and 622.08MHz.
All devices support two types of differential output dri-
vers: LVDS and LVPECL. When the OE signal is low,
LVPECL outputs go to the PECL_BIAS level of
V
CC
- 2.0V, while the LVDS outputs are a logical one.
See Figures 2 and 3 for an LVDS and LVPECL output
timing diagram.

data sheet at www.maxim-ic.com/DS4106.
