DS4M133D+33

Programmable Timers And Oscillators Overview

The DS4M133D+33 is a 3.3V margining clock oscillator generating a nominal frequency of 133.33MHz with LVDS outputs. It utilizes a low-jitter PLL and an AT-cut fundamental-mode crystal to achieve typical phase jitter below 0.9ps RMS (12kHz to 20MHz). The device supports ±5% frequency deviation via the MS pin, operating from a single 3.3V supply with current consumption under 100mA. It features an active-high OE input for output enable/disable and operates within a -40°C to +85°C temperature range in a 5mm x 3.2mm ceramic LCCC package.

Programmable Timers And Oscillators Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm lead-free status (+ suffix indicates JESD97 category e4 Au over Ni finish). Ensure compatibility with RoHS and REACH regulations. Check datasheet revision history for any parameter updates before finalizing procurement specifications.

Programmable Timers And Oscillators Selection Notes

Select the DS4M133D+33 when a 133.33MHz clock with LVDS signaling is required. Choose this part over the 'P' variant if LVDS is preferred over LVPECL. Ensure the design accommodates the 5mm x 3.2mm LCCC footprint and provides appropriate termination resistors for LVDS loads. Verify that the system power supply remains within the 3.135V to 3.465V range for optimal performance.

Programmable Timers And Oscillators Part Context

This component belongs to the DS4M125/DS4M133/DS4M200 family of 3.3V margining clock oscillators. The 'D' suffix denotes LVDS output capability, while 'P' indicates LVPECL. The '+33' suffix specifies the 3.3V operating voltage and lead-free packaging. These devices are designed to integrate with external crystals to form complete oscillator solutions for high-speed digital systems.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes include DS4M125D+33 (125MHz) and DS4M200D+33 (200MHz) from the same family. For LVPECL outputs, consider DS4M133P+33. Verify pinout compatibility and output driver characteristics when substituting. No other cross-family replacements are documented.
