The high-precision HOSONIC TCXO empowers handheld navigation devices with accurate positioning capabilities.

Handheld navigation devices, as core terminal equipment in modern positioning and navigation fields, are widely used in outdoor exploration, vehicle navigation, logistics tracking, and surveying and exploration scenarios. These devices need to achieve rapid positioning, trajectory recording, and data transmission in complex and changing environments. Therefore, they have stringent requirements for the precision, power consumption, reliability, and environmental adaptability of hardware systems. Mainstream hardware selection schemes are typically built around high-performance main control chips, high-sensitivity RF receiving modules, and low-power power management units. The choice of clock reference devices is one of the key factors determining system performance.

Temperature-compensated crystal oscillators (TCXOs) have become the preferred solution in the hardware design of handheld navigation devices due to their unique temperature compensation mechanisms. Compared with ordinary crystal oscillators, TCXOs can monitor environmental temperature changes in real-time and dynamically adjust the output frequency through the collaborative work of built-in thermistors, compensation networks, and integrated circuits. This process improves frequency stability to the ppm level, effectively solving the problem of clock signal accuracy affected by temperature fluctuations. It ensures stable clock output for navigation devices within a wide temperature range of -40℃ to 85℃, providing precise time references for satellite signal decoding, data processing, and communication protocol operation.

In the RF front-end and digital signal processing modules of handheld navigation devices, TCXOs in the 9.6~52MHz frequency band play a key role in frequency supply. This frequency range not only meets the clock input requirements of mainstream navigation chipsets but also matches the local oscillator signal requirements of the RF chain. Specifically, the TCXOs in this frequency band, with their low phase noise design, can reduce phase distortion in the signal demodulation process and improve satellite signal acquisition sensitivity. This is especially significant for improving positioning accuracy in multipath fading or signal-blocking scenarios. Their stable frequency output can also reduce timing errors in digital signal processing, ensuring the accuracy of navigation data parsing. To extend the effective working time of handheld devices, the 9.6~52MHz TCXOs have innovatively applied low-power design schemes. Under the premise of ensuring high-precision frequency output performance, the current consumption is reduced to the microampere level. Combined with intelligent power management strategies, this effectively solves the endurance problem in mobile scenarios. This optimized combination of frequency range and performance parameters makes it an ideal choice for balancing navigation accuracy, power consumption control, and cost-effectiveness.

Hosonic's 9.6~52MHz G32TC TCXO has shown significant advantages in handheld navigation device applications with its excellent technical parameters and reliable performance. The product uses a compact 3.2×2.5mm package, which is highly compatible with the miniaturization design trend of handheld devices and is convenient for PCB layout and integration. Its frequency stability can reach ±0.5ppm (-20℃ to 70℃) and maintain a stable output of ±2ppm within the full temperature range, meeting the high-precision requirements of GNSS (Global Navigation Satellite System) for clock references. Through advanced MEMS processes and vacuum packaging technology, the G32TC has achieved a wide operating temperature range of -40℃ to 85℃, enabling stable operation in extreme environments. In terms of power consumption control, the typical working current is only 2.5mA (3.3V power supply), effectively reducing system energy consumption.
