DS4425BN+

Programmable Timers And Oscillators Overview

The DS4425BN+ is a ceramic surface-mount crystal oscillator generating a fixed 425.00MHz clock frequency. It utilizes fundamental crystal technology combined with PLL circuitry to achieve low phase jitter and noise performance, with typical RMS jitter of 0.9ps from 12kHz to 20MHz. The device operates on a 3.3V ±10% supply voltage and features LVDS output drivers. It is housed in a compact 10-pin LCCC package measuring 5.0mm x 3.2mm x 1.49mm, designed for applications requiring precise timing within tight PCB space constraints.

Programmable Timers And Oscillators Procurement Notes

Verify the component status as discontinued or end-of-life through official manufacturer channels before procurement planning. Confirm that the 'B' suffix specifically denotes the LVDS output variant required for the design. Ensure compatibility with lead-free soldering processes given the Au over Ni lead finish specification.

Programmable Timers And Oscillators Selection Notes

Select the DS4425BN+ when a 425MHz clock signal with LVDS outputs is required. Choose the 'A' suffix version if LVPECL outputs are needed instead. Verify that the system power supply remains within the 3.0V to 3.6V range to maintain specified frequency stability and current consumption parameters.

Programmable Timers And Oscillators Part Context

This component belongs to the Maxim DS4-XO series of precision clock oscillators. It shares the same physical package and general electrical characteristics with the DS4106AN+/BN+ (106.25MHz) and DS4212AN+/BN+ (212.50MHz). The primary distinction between these family members is the generated output frequency determined by the internal PLL divider ratios.
