DS4-XO Series Crystal Oscillators
General Description
The DS4125, DS4155, DS4156, DS4160, DS4311, DS4312, DS4622, and DS4776 ceramic surface-mount crystal oscillators are part of Maxim’s DS4-XO series crystal oscillators family. These devices offer output frequencies at 125MHz, 155.52MHz, 156.25MHz, 160MHz, 311.04MHz, 312.5MHz, 622.08MHz, and 77.76MHz. The clock oscillators are suited for systems with tight tolerances because of the jitter, phase noise, and stability performance. The small package provides a format made for applications where PCB space is critical.
These clock oscillators are crystal based and use a fundamental crystal with PLL technology to provide the final output frequencies. Each device is offered with LVDS or LVPECL output types. The output enable pin is active-high logic.
These clock oscillators have very low phase jitter and phase noise. Typical phase jitter is < 0.6psRMS from 12kHz to 20MHz. The devices are designed to operate with a 3.3V ±5% supply voltage, and are available in a 5.0mm x 3.2mm x 1.49mm, 10-pin LCCC surface-mount ceramic package.

Specification
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
