Detailed Description
The DS4266 consists of a fundamental-mode crystal
and synthesizer IC packaged in a 5mm x 3.2mm x
1.49mm, 10-pin LCCC ceramic package. The device
produces a frequency output of 266.00MHz. Two differ-
ential output types are available: LVDS and LVPECL.
The device output can be enabled or disabled through
the OE signal input. When the OE signal is low, LVPECL
outputs go to the PECL_BAS level of VCC - 2.9V, while
the LVDS outputs are a logical 1. See Figures 2 and 3
for LVDS and LVPECL output timing diagrams.
Additional Information
For more available frequencies in the DS4-XO family,
