The DS4266 surface-mount ceramic crystal oscillator is
part of Maxim’s DS4-XO crystal oscillator product fami-
ly. 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 0.7ps
12kHz to 20MHz bandwidth, and duty-cycle perfor-
mance 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 conjunc-
tion with high-performance silicon germanium PLL tech-
nology, 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.
