ABDFTCXO-10.000MHZ-E-2-T5

Oscillators Overview

The ABDFTCXO-10.000MHZ-E-2-T5 is a dual-output Stratum-III SMD TCXO/VCTCXO operating at 10.000 MHz with LVCMOS outputs. It provides coherent F0 and F0÷2 signals via an integrated precision fan-out buffer. The device meets ±280 ppb Stratum-III stability requirements and features ±1 ppm aging, ensuring ±4.6 ppm total accuracy over its lifecycle. Standard frequencies range from 5 to 52 MHz. It operates on a 3.3V supply with a maximum current of 20 mA within a -40°C to +85°C temperature range.

Oscillators Feature Summary

• Dual-output capability delivering phase and frequency coherent F0 and F0÷2 signals through an integrated precision fan-out buffer for stable clock distribution.
• High-precision stability meeting Stratum-III requirements with ±280 ppb initial tolerance and ±1 ppm aging characteristics for long-term accuracy.
• Flexible configuration allowing selection between TCXO and VCTCXO functions, with VCTCXO variants offering specific pullability and linear tracking.

Oscillators Applications

• Synchronous Ethernet IEEE1588 networks
• GPS and RTLS positioning systems
• Microcellular (BTS) and femtocell infrastructure

Oscillators Procurement Notes

This component has been officially designated as End-of-Life (EOL) due to the termination of production capabilities. The Engineering Change Notice (ECN/PCN) number 3707 confirms this status with an effective date of November 10, 2020. Procurement channels are no longer accepting new orders for this specific part number. Designers must verify that any existing stock is not subject to immediate obsolescence restrictions and should initiate replacement planning immediately to avoid project delays.

Oscillators Selection Notes

Selection of this part requires acknowledgment of its discontinued status. While it offers high stability and dual outputs suitable for synchronization applications, availability is strictly limited to pre-existing inventory. Engineers evaluating this component for new designs must prioritize alternative solutions that ensure long-term supply chain continuity. The decision to use this part should be based on legacy compatibility rather than new procurement potential.

Oscillators Part Context

The ABDFTCXO-10.000MHZ-E-2-T5 belongs to Abracon's Stratum-III series of temperature-compensated crystal oscillators. It was designed for applications requiring precise timing and frequency coherence in communication and networking equipment. The device integrates both TCXO and VCTCXO functionalities within a single surface-mount package, catering to diverse system clocking needs before its retirement from the product line.

Oscillators Replacement Considerations

The official substitute part number specified by the manufacturer is AK7. Users transitioning from this EOL component should evaluate the AK7 series for pinout compatibility and electrical parameter alignment to ensure seamless integration into existing designs without significant circuit modifications.
