NKEEELJNNY-20.000000

Oscillators Overview

The Taitien NKEEELJNNY-20.000000 is a 20 MHz Oven Controlled Crystal Oscillator (OCXO) designed for high-stability timing applications. It operates on a single 3.3V supply voltage and delivers a CMOS output signal. The component utilizes a 6-SMD, No Lead surface-mount package with dimensions of 14.5 mm x 9.6 mm x 6.5 mm. It features a standard temperature stability of ±30 ppb across the -40°C to +85°C operating range and supports frequency adjustment up to 5 ppm. Maximum current consumption is specified at 600 mA.

Oscillators Feature Summary

• High-frequency stability achieved through integrated oven control technology
• CMOS output interface compatible with digital logic circuits
• Robust thermal performance across wide industrial temperature ranges
• Compact surface-mount packaging for automated assembly

Oscillators Applications

• SDH/SONET telecommunications base stations
• High-reliability commercial systems
• Critical mission defense electronics
• Precision test and measurement instrumentation
• Reference timing circuits for packet time protocol 1588

Oscillators Procurement Notes

Verify that the specific part number matches the required oven-controlled crystal oscillator specifications, particularly the 20 MHz frequency and CMOS output type. Confirm the 3.3V supply requirement and 600 mA maximum current draw align with the system power budget. Ensure the physical footprint of the 14.5 mm x 9.6 mm x 6.5 mm package fits the designated PCB layout area. Check for RoHS compliance status if environmental regulations apply to the end product.

Oscillators Selection Notes

Select this component when superior phase noise and long-term frequency stability are critical compared to standard TCXOs or VCXOs. The OCXO architecture provides consistent performance over varying ambient temperatures without external compensation. Consider the higher power consumption relative to other oscillator types due to the internal heating element. This model is suitable for applications requiring Stratum 3 level timing accuracy in compact form factors.

Oscillators Part Context

This oscillator belongs to Taitien's NK-N series of oven-controlled crystal oscillators. The series is engineered for demanding environments where precise frequency reference is essential. The manufacturer specializes in quartz frequency control products, offering a range of timing solutions from basic crystals to atomic clocks. The NK-N series specifically targets telecom and defense sectors requiring high reliability.

Oscillators Replacement Considerations

Direct substitutes within the same series include the NKEECCJNNY-20.000000 variant, which shares identical electrical characteristics and pinout configuration. Both parts operate at 20 MHz with 3.3V CMOS outputs. Verify mechanical compatibility before substitution, as both utilize the same 6-SMD no-lead package dimensions.
