DDR Clock Oscillator

Active: In Production.

The DS4266 surface-mount ceramic crystal oscillator is part of Maxim's DS4-XO crystal oscillator product family. The DS4266 is a 266MHz crystal oscillator designed to support high-performance DDR memory applications that require a stable, low-jitter, and tight duty-cycle clock source. The device provides an overall accuracy and stability better than ±50ppm, including aging. Jitter performance is better than 0.7psRMS typically over a 12kHz to 20MHz bandwidth, and duty-cycle performance is better than 48%/52%.

The DS4266 has an output frequency of 266MHz, and it supports LVDS and LVPECL output types. The DS4266 is constructed using a fundamental crystal in conjunction with high-performance silicon germanium PLL technology, enabling very low phase noise and phase jitter performance. The device operates from a 3.3V ±5% power supply and consumes a maximum current of 100mA.

The DS4266 is packaged in a miniature 5mm x 3.2mm x 1.49mm, 10-lead LCCC ceramic package, making it suitable for applications where board space is critical.
