EB13E2C2H-40.000M TR

Oscillators Overview

The EB13E2C2H-40.000M TR is a standard clock oscillator manufactured by Ecliptek, operating at a nominal frequency of 40 MHz with a maximum frequency stability of ±100 ppm over the -20°C to +70°C temperature range. It utilizes a 3.3 Vdc supply voltage and features an LVCMOS output format. The device is housed in a 4-pad ceramic surface-mount package measuring 3.2 mm x 2.5 mm. Key electrical specifications include a maximum current consumption of 5 mA, a load capacitance of 15 pF, and a tri-state enable/disable function. The component supports CMOS logic levels with defined high and low voltage thresholds.

Oscillators Feature Summary

• Provides stable 40 MHz timing signals with ±100 ppm total frequency tolerance across the commercial temperature range.
• Integrates a tri-state control mechanism allowing for high-impedance output disable via dedicated enable pins.
• Delivers robust LVCMOS signal integrity with defined drive capabilities suitable for direct interfacing with digital loads.

Oscillators Applications

• General-purpose microcontroller clock generation
• Ethernet PHY interface synchronization
• Serial communication port expansion circuits

Oscillators Procurement Notes

Verify that the specific part number EB13E2C2H-40.000M TR matches the required -20°C to +70°C operating temperature range, as other variants in the series support industrial ranges. Confirm the ±100 ppm stability requirement aligns with system timing constraints. Ensure the 3.3V supply voltage is compatible with the target board design before procurement.

Oscillators Selection Notes

Select this component when a 40 MHz clock source is required for commercial-grade applications within the -20°C to +70°C range. The ±100 ppm stability is sufficient for standard UART, SPI, or I2C interfaces but may be insufficient for high-speed synchronous protocols requiring tighter tolerances. Consider the 5 mA current draw for power budget calculations in battery-operated devices.

Oscillators Part Context

This oscillator belongs to the EB13E2 series of standard SPXO components from Ecliptek. The series offers various frequencies and stability grades in a compact 3225 ceramic package. This specific model represents the commercial temperature variant with moderate stability, distinguishing it from higher-precision industrial versions like the EB13E2J2H series.

Oscillators Replacement Considerations

Direct substitutes within the same series include EB13E2D2H-40.000M TR (±25ppm) and EB13E2E2H-40.000M TR (±50ppm). Cross-brand replacements must match the 3.2x2.5mm footprint, 3.3V supply, and LVCMOS output characteristics.
