NDK quartz crystal oscillators drive the innovation of in-vehicle video terminals.

With the rise of intelligent connected vehicles, in-vehicle video terminals, as a key component of vehicle intelligence, undertake important responsibilities such as navigation, entertainment, and safety monitoring. In hardware selection, high-performance and high-stability core components are crucial to ensuring reliable system operation. Current mainstream in-vehicle video terminal solutions typically adopt multi-core processors (such as Rockchip RK3588 and Qualcomm SA8155P) paired with high-speed memory and storage modules, integrating 4G/5G communication, Wi-Fi/Bluetooth modules, and high-precision GPS positioning chips. In this architecture, quartz crystal oscillators, as the "electronic heart," provide precise clock signals for each module, ensuring data synchronization and system timing accuracy. Compared with ordinary oscillators, quartz crystal oscillators significantly enhance the reliability of video coding/decoding, multi-screen interaction, and real-time communication with their high frequency stability (within ±20ppm), low phase jitter (typical 85fs), and wide-temperature operation capability (-40°C to +125°C), especially suitable for temperature fluctuations and mechanical vibrations in vehicle environments.  

Quartz crystal oscillators play a pivotal role across core functional modules in in-vehicle video terminals. For example, the main control chip relies on the reference clock provided by the oscillator to coordinate data processing and instruction execution; communication modules (such as 5G modules) stabilize radio frequency signal frequencies through the oscillator to reduce data transmission bit error rates; audio processing units require low-jitter clock signals to ensure audio-video synchronization and sound quality clarity. The environmental tolerance of quartz crystal oscillators is one of their core advantages. Automotive-grade products certified by AEC-Q200 feature anti-vibration and impact resistance, maintaining long-term stable operation under complex working conditions, while their performance parameters are also extremely excellent. Additionally, miniaturized packaging (such as 3.2×2.5mm) adapts to the compact PCB layout requirements of in-vehicle terminals, while low-power consumption further optimizes system energy efficiency.  

To meet the high standards of in-vehicle video terminals, NDK (Nihon Dempa Kogyo Co., Ltd.) has introduced the NP3225SC differential crystal oscillator as an industry benchmark. This oscillator features HCSL output, a frequency range of 100MHz to 175MHz, and ultra-low phase jitter of 85fs@156.25MHz, meeting the timing precision requirements for high-speed data transmission. It supports power voltages of +2.5V or +3.3V, compatible with mainstream in-vehicle chip power supply schemes, with a maximum current consumption of only 50mA, significantly reducing system power consumption. The NP3225SC is AEC-Q200 certified, supports a wide operating temperature range of -40°C to +105°C, and adopts a solder crack-resistant design to ensure long-term stable operation in harsh environments. As an official authorized agent of NDK, MANDU provides comprehensive selection support and customized services, including parameter matching, fast sample delivery, and technical solution optimization, dedicated to helping enterprises shorten development cycles and enhance product competitiveness.  

For R&D engineers of in-vehicle video terminals, choosing NDK quartz crystal oscillators is not only a performance guarantee but also a commitment to reliability. Their high-precision clock signals effectively reduce system timing errors and improve multi-module collaboration efficiency; automotive-grade design and full-temperature stability significantly reduce failure risks caused by environmental factors. Combined with MANDU’s professional technical support and supply chain services, NDK oscillators provide complete solutions from hardware to application layers for in-vehicle audio-visual systems such as smart cockpits and dash cams. In the wave of automotive electronics integration with intelligence and connectivity, NDK quartz crystal oscillators continue to drive in-vehicle terminals toward higher performance and better user experience with their exceptional quality.
