DS4M125D+33

Programmable Timers And Oscillators Overview

The DS4M125D+33 is a 3.3V margining clock oscillator with LVDS outputs, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.135V to 3.465V and supports a nominal frequency of 125MHz. The device integrates a low-jitter PLL, achieving typical phase jitter of less than 0.9ps RMS from 12kHz to 20MHz. Frequency margining allows for ±5% deviation control via the MS pin. Operating current ranges from 52mA to 75mA depending on load conditions. The component is housed in a 10-pin LCCC package (5mm x 3.2mm) and functions across an industrial temperature range of -40°C to +85°C.

Programmable Timers And Oscillators Feature Summary

• Frequency Margining: Supports ±5% frequency deviation via a three-level MS input pin.
• Low Jitter Performance: Typical integrated phase jitter is < 0.9ps RMS (12kHz to 20MHz).
• LVDS Output Interface: Provides differential LVDS signals with 425mV typical differential output voltage.
• Single Supply Operation: Functions on a single 3.3V supply with operating current under 100mA.

• Memory Clock Generation
• RAID Systems

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix '+33' against official documentation to confirm lead-free status and package variant. Confirm availability through authorized distributors as this component may be subject to discontinuation notices or limited stock constraints. Ensure the selected part matches the required LVDS output configuration.

Programmable Timers And Oscillators Selection Notes

Select the DS4M125D+33 when a 125MHz clock with LVDS signaling and frequency margining capability is required. Compare against the DS4M125P+33 if LVPECL outputs are preferred instead of LVDS. Ensure the application circuit provides appropriate termination resistors for the LVDS interface and manages power supply noise to maintain jitter specifications.

Programmable Timers And Oscillators Part Context

This component belongs to the DS4M series of 3.3V margining clock oscillators, which also includes the DS4M133 and DS4M200 variants. These devices share a common 10-LCCC ceramic package and utilize fundamental-mode crystals to form complete clock oscillators. The 'D' designation indicates the LVDS output option, while 'P' denotes LVPECL.
