ECS-P143-AN

Overview

The ECS-P143-AN is a programmable crystal oscillator manufactured by ECS Inc., designed for through-hole mounting in a 14-DIP metal can package. It operates on a 3.3V supply with a maximum current consumption of 28mA. The device supports an HCMOS output signal and offers a frequency range from 1 MHz to 125 MHz, which is customized via DigiKey programming during the ordering process. It features an enable/disable function and maintains a total frequency stability of ±100ppm across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports user-defined frequency selection within the 1 MHz to 125 MHz range through distributor programming services.
• Integrates an enable/disable control function for power management flexibility.
• Delivers standard HCMOS logic output signals suitable for digital circuit interfacing.

Applications

• Clock generation for general-purpose digital logic circuits
• Timing reference sources for embedded microcontroller systems
• Synchronization modules requiring specific frequency customization

Procurement Notes

Verify that the required frequency falls within the 1 MHz to 125 MHz operational range before placing orders. Confirm that the system design accommodates the 3.3V supply voltage and 28mA maximum current draw. Ensure compatibility with the 14-DIP through-hole footprint dimensions. Check RoHS compliance status as the component is noted as non-compliant in available documentation. Review lead times associated with the custom programming service provided by distributors.

Selection Notes

Select this model when a fixed-frequency crystal is insufficient and a specific clock rate between 1 MHz and 125 MHz is required without internal configuration registers. Choose the ECS-P143-AN over the ECS-P143-B variant if operation in temperatures down to -40°C is necessary, as the B series is limited to 0°C minimum. Consider the HCMOS output swing requirements of the receiving logic gates. Evaluate the physical space constraints for the full-size metal DIP package against PCB layout limitations.

Part Context

This component belongs to the ECS-P143 series of programmable oscillators, sharing the same 14-DIP metal can form factor and basic electrical architecture as other variants like the ECS-P143-B. It differs primarily in its extended low-temperature rating compared to commercial grade options. The series represents a solution for applications needing precise, non-standard frequencies generated at the factory rather than adjustable via external pins.

Replacement Considerations

The ECS-P143-B is a direct functional substitute within the same series but offers reduced temperature stability (0°C to 70°C). No other cross-model replacements are confirmed in public documentation. Verify pinout compatibility and voltage levels when substituting.
