• Manufacturer Part Number: ds4266
• Description: Ddr Clock Oscillator
• Manufacturer: Maxim Integrated Products, Inc.

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
