DS4312D+

Programmable Timers And Oscillators Overview

The DS4312D+ is a ceramic surface-mount crystal oscillator from the Maxim DS4-XO series, manufactured by Analog Devices Inc./Maxim Integrated. It generates a nominal output frequency of 312.50 MHz with an initial tolerance of ±20 ppm and total stability of ±50 ppm over temperature. The device operates on a 3.135V to 3.465V supply and consumes up to 75 mA in LVDS mode. It features integrated phase jitter of less than 0.7ps RMS (12kHz to 20MHz) and utilizes PLL technology with a fundamental AT-cut crystal. The component is housed in a 10-pin LCCC package measuring 5.0mm x 3.2mm x 1.49mm.

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'D+' indicates a lead-free/RoHS-compliant package with JESD97 category e4 (Au over Ni) finish. Confirm the part status as active or discontinued through official manufacturer channels before procurement planning.

Programmable Timers And Oscillators Selection Notes

Select the DS4312D+ for applications requiring a precise 312.50 MHz clock signal with low jitter performance. Ensure the design supports the required 3.3V ±5% supply voltage and accommodates the 10-pin LCCC footprint. Verify that the LVDS output driver matches the load requirements of the receiving circuitry.

Programmable Timers And Oscillators Part Context

This component belongs to the DS4-XO series of ceramic surface-mount crystal oscillators. It shares the same physical package dimensions and general electrical characteristics with other models in the family, such as the DS4311D+ and DS4300D+, differentiated primarily by their nominal output frequencies.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same series include the DS4312P+ for LVPECL output or other DS4-XO models like DS4311D+ if the frequency difference is acceptable. Cross-model substitution requires verifying frequency compatibility and output driver type.
