Different Types of TKD Crystal Oscillators

SPXO Crystal Oscillators

TKD specializes in high-stability SPXO (Simple Packaged Crystal Oscillators). Featuring a fully integrated internal oscillation circuit, these active oscillators are designed for seamless plug-and-play integration. Our comprehensive product lineup includes programmable, wide-temperature, and AEC-Q compliant (automotive-grade) models. Engineered for superior frequency stability, they are extensively deployed in telecommunications infrastructure, servers, and automotive electronics.

TCXO Oscillators

TKD specializes in high-precision, wide-temperature TCXOs (Temperature Compensated Crystal Oscillators). Equipped with advanced temperature compensation networks, our TCXOs effectively mitigate frequency drift over temperature. Our comprehensive product portfolio includes low-voltage, low-phase-noise, and AEC-Q compliant (automotive-grade) models. Widely deployed in satellite navigation, RF communications, and automotive electronics, these oscillators guarantee stable and reliable clock signals even in extreme operating environments.

Differential Oscillators (Low Jitter)

TKD specializes in low-jitter differential crystal oscillators (DXOs). Utilizing LVDS/LVPECL differential output architectures, these oscillators offer exceptional immunity to electromagnetic interference (EMI) and ultra-low phase jitter. Widely deployed in 5G base stations, AI computing clusters, and high-speed optical transceivers, our DXOs deliver high-integrity clock signal solutions tailored for high-frequency, high-speed communication applications.

OCXO Oscillators

TKD specializes in ultra-low phase noise and high-precision OCXOs (Oven Controlled Crystal Oscillators). Utilizing advanced oven-controlled technology, these oscillators effectively isolate frequency outputs from ambient temperature fluctuations. Featuring exceptionally low aging rates and superior phase noise performance, our OCXOs are widely deployed in satellite communications, radar systems, and precision test and measurement equipment, delivering the ultimate frequency reference for demanding, high-end applications.

Customer Recognition
Recognized by Leading Global Manufacturers

TKD is the first crystal oscillator manufacturer globally to receive official certification from Qualcomm's next-generation flagship computing platform for AI glasses (Snapdragon AR1+ Gen 1). Rigorous testing by Qualcomm has validated the superior performance of TKD's products in terms of impedance, ultra-low power consumption, and frequency consistency across a wide temperature range. Consequently, these products have been officially included in Qualcomm's global recommended bill of materials.

AI Wearables

TKD is the first domestic crystal oscillator manufacturer to pass Qualcomm's automotive-grade 5G platform certification. Its independently developed 38.4MHz automotive-grade thermosensitive crystal has successfully passed Qualcomm's stringent qualification, setting a new record for the widest operating temperature range (-40°C to 115°C) in Qualcomm's automotive certifications and breaking the technological monopoly previously held by international manufacturers.

Automotive Electronics

TKD maintains deep strategic partnerships with leading global optical transceiver manufacturers, including Innolight and Eoptolink. Its 625MHz ultra-low-jitter differential crystal oscillators, featuring a phase jitter as low as 15 femtoseconds, match or even surpass the performance of international industry giants. These oscillators have been successfully integrated into 800G and 1.6T high-speed optical transceivers, successfully filling the domestic gap in high-end computing clock solutions.
