DS4125P+

Programmable Timers And Oscillators Overview

The DS4125P+ is a ceramic surface-mount crystal oscillator from the Maxim DS4-XO series, operating at a nominal frequency of 125MHz. It features LVPECL output drivers and operates on a 3.3V ±5% supply voltage. The device utilizes fundamental AT-cut crystal technology with PLL synthesis to achieve low phase jitter (<0.7ps RMS from 12kHz to 20MHz) and high stability (±50ppm total over temperature). Housed in a compact 10-pin LCCC package measuring 5.0mm x 3.2mm x 1.49mm, it supports an operating temperature range of -40°C to +85°C.

Programmable Timers And Oscillators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status (JESD97 category e4 finish). Check current availability as this specific part number may be subject to discontinuation notices; consult official documentation for lifecycle status before procurement planning.

Programmable Timers And Oscillators Selection Notes

Select DS4125P+ for applications requiring 125MHz LVPECL clock signals with tight jitter specifications. Ensure PCB layout accommodates the 10-pin LCCC footprint and provides adequate thermal dissipation. Verify that system power supplies maintain 3.3V ±5% tolerance to meet electrical characteristics. Consider the DS4125D+ variant if LVDS outputs are required instead.

Programmable Timers And Oscillators Part Context

The DS4125P+ belongs to the Maxim DS4-XO series of crystal oscillators, which includes variants like DS4156P+, DS4150P+, and DS4625P+. These devices share common packaging and operational principles but differ in output frequencies and driver types. The 'P+' suffix indicates LVPECL output and RoHS-compliant packaging, while 'D+' denotes LVDS output.

Programmable Timers And Oscillators Replacement Considerations

For equivalent functionality, consider the DS4125D+ for LVDS output or other DS4-XO series members with matching frequencies. Verify pin compatibility and electrical parameters against target designs. Consult official datasheets for any updated revisions or alternative part numbers recommended by Analog Devices/Maxim Integrated.
