DS4-XO Series Crystal Oscillators
General Description
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 < 0.7psRMS 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.

Detailed Description
The devices consist of a fundamental-mode, AT-cut crystal and a synthesizer IC that can synthesize any one of these frequencies: 77.76MHz, 125MHz, 150MHz, 155.52MHz, 156.25MHz, 160MHz, 250MHz, 300MHz, 311.04MHz, 312.5MHz, and 622.08MHz. All devices support two types of differential output drivers: LVDS and LVPECL. When the OE signal is low,
LVPECL outputs go to the PECL_BIAS level of VCC - 2.0V, while the LVDS outputs are a logical one. See Figures 2 and 3 for an LVDS and LVPECL output timing diagram.

Revision History
REVISION NUMBER 0 REVISION DATE 7/07 Initial release. Added DS4150, DS4250, DS4300. 1 3/08 Removed f INITIAL from the frequency stability calculation in Note 3. In the Pin Description, changed the EP description to indicate that it should not be connected and to avoid placing exposed metal under the pad location. 2 6/08 Removed future status from the DS4150, DS4250, and DS4300. DESCRIPTION PAGES CHANGED -- All 3 4 1, 6
