DS4125DS4776 Rev 2 6/08 DS4-XO Series Crystal Oscillators General Description Features The DS4125, DS4150, DS4155, DS4156, DS4160, < 0.7ps from 12kHz to 20MHz Jitter RMS DS4250, DS4300, DS4311, DS4312, DS4622, and LVDS or LVPECL Output Types DS4776 ceramic surface-mount crystal oscillators are 3.3V Operating Voltage part of Maxims DS4-XO series of crystal oscillators. These devices offer output frequencies at 125MHz, 5.0mm x 3.2mm x 1.49mm, 10-Pin LCCC Ceramic 155.52MHz, 156.25MHz, 160MHz, 311.04MHz, 312.5MHz, Package 622.08MHz, and 77.76MHz. The clock oscillators are -40C to +85C Operating Temperature Range suited for systems with tight tolerances because of the Lead-Free/RoHS Compliant jitter, phase noise, and stability performance. The small package provides a format made for applications Ordering Information where PCB space is critical. These clock oscillators are crystal based and use a fun- PART TEMP RANGE PIN-PACKAGE damental crystal with PLL technology to provide the DS4125D+ -40C to +85C 10 LCCC final output frequencies. Each device is offered with DS4125P+ -40C to +85C 10 LCCC LVDS or LVPECL output types. The output enable pin is active-high logic. DS4150D+ -40C to +85C 10 LCCC DS4150P+ -40C to +85C 10 LCCC These clock oscillators have very low phase jitter and phase noise. Typical phase jitter is < 0.7ps from RMS DS4155D+ -40C to +85C 10 LCCC 12kHz to 20MHz. The devices are designed to operate DS4155P+ -40C to +85C 10 LCCC with a 3.3V 5% supply voltage, and are available in a DS4156D+ -40C to +85C 10 LCCC 5.0mm x 3.2mm x 1.49mm, 10-pin LCCC surface-mount DS4156P+ -40C to +85C 10 LCCC ceramic package.
