Part Number	Replacement	Explanation

Description

Create a design and simulate using EE-Sim^® tools:

The DS4125, DS4150, DS4155, DS4156, DS4160, DS4250, DS4300, DS4311, DS4312, DS4622, and DS4776 ceramic surface-mount crystal oscillators are part of Maxim's DS4-XO series of crystal oscillators. 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 < 0.7ps_RMS 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.
