DS4212AN+

Programmable Timers And Oscillators Overview

The DS4212AN+ is a ceramic surface-mount crystal oscillator from the DS4-XO series, manufactured by Analog Devices Inc./Maxim Integrated. It generates a fixed clock output frequency of 212.5MHz using fundamental crystal technology combined with PLL circuitry. The device features LVPECL outputs and operates on a 3.0V to 3.6V supply voltage, drawing a typical current of 50mA at +3.3V when unloaded. It provides low phase jitter (typically < 0.9ps RMS from 12kHz to 20MHz) and maintains frequency stability within ±39ppm over the operating temperature range of -40°C to +85°C. The component is housed in a compact 10-pin LCCC package measuring 5.0mm x 3.2mm x 1.49mm.

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'A' confirms LVPECL outputs, as the 'B' suffix indicates LVDS. Confirm lead-free status via the '+' designation, which denotes JESD97 category e4 (Au over Ni) finish compatible with both lead-based and lead-free soldering processes. Check for RoHS compliance documentation if required for specific manufacturing standards.

Programmable Timers And Oscillators Selection Notes

Select the DS4212AN+ when an LVPECL interface is required for the 212.5MHz application; use the DS4212BN+ variant for LVDS requirements. Ensure the system design accommodates the 50mA typical supply current and provides appropriate termination resistors (100Ω for LVPECL). Verify that the PCB layout supports the 10-LCCC package dimensions and thermal dissipation characteristics.

Programmable Timers And Oscillators Part Context

This component belongs to the Maxim DS4-XO series of precision ceramic surface-mount crystal oscillators. It shares the same physical package and general electrical architecture with the DS4106 (106.25MHz) and DS4425 (425MHz) models. The primary distinction between these family members is the generated output frequency, while maintaining consistent jitter performance and package form factors.
