EB13E2H2H-33.333M TR

Oscillators Overview

The EB13E2H2H-33.333M TR is a standard quartz crystal oscillator (SPXO) manufactured by Ecliptek, operating at a nominal frequency of 33.333 MHz. It utilizes an LVCMOS output format and requires a single 3.3 Vdc supply voltage with a tolerance of ±5%. The device features a maximum frequency stability of 50 ppm over the industrial temperature range of -40°C to +85°C. Packaged in a 4-pad ceramic surface-mount (SMD) footprint measuring 3.2 mm x 2.5 mm, it supports tri-state control for power management. Key electrical specifications include a maximum current consumption of 4 mA, a load capacitance of 15 pF, and a maximum RMS phase jitter of 1 ps within the 12 kHz to 20 MHz bandwidth.

Oscillators Feature Summary

• Provides precise clock generation via LVCMOS output compatible with standard digital logic interfaces.
• Features tri-state enable/disable functionality allowing for low-power standby modes with minimal quiescent current.
• Constructed in a compact ceramic surface-mount package suitable for high-density PCB layouts.
• Ensures signal integrity with low phase jitter performance across the specified operating temperature range.

Oscillators Applications

• Industrial gateway and controller clock synchronization
• Ethernet PHY interface timing reference
• High-speed serial communication bus clocks
• Consumer electronics requiring stable 3.3V logic timing

Oscillators Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm that the 50 ppm stability rating aligns with system requirements for the -40°C to +85°C range. Ensure the design accommodates the 3.3V supply rail and includes necessary decoupling capacitors near the power pin as per datasheet recommendations. Check RoHS compliance documentation if required for regulatory standards.

Oscillators Selection Notes

Select this component when a 33.333 MHz frequency is required for CMOS-compatible circuits. The 50 ppm stability offers a balance between cost and performance for general industrial applications. Consider the 4 mA current draw for battery life calculations. If tighter stability or different temperature ranges are needed, evaluate other variants within the EB13E2 series such as those with 25 ppm or 100 ppm ratings.

Oscillators Part Context

This part belongs to the EB13E2 series of standard quartz crystal oscillators from Ecliptek. The series covers frequencies from 1.024 MHz to 66.6666 MHz with various stability options. The EB13E2H2H variant specifically denotes the industrial temperature grade (-40°C to +85°C) and 50 ppm stability. The series is designed for replaceability of discrete crystal resonators and buffer amplifiers in modern embedded systems.

Oscillators Replacement Considerations

Direct substitutes must match the 33.333 MHz frequency, 3.3V operation, LVCMOS output, and 3225 package size. Verify equivalent stability (±50 ppm) and temperature range compatibility. Cross-reference with Abracon equivalents if available, ensuring pinout and electrical characteristics remain identical to avoid redesign.
