In today's rapidly developing era of intelligent vehicles, the complexity and performance requirements of electronic systems are growing exponentially. From ADAS advanced driving assistance to in vehicle sensor networks, from intelligent cockpits to electric drive systems, every link relies on precise clock signals as a "metronome" for coordinated operation. The SG-8201CJA automotive grade crystal oscillator launched by Epson is a clock solution tailored for this era, with core advantages such as high precision, low jitter, wide temperature range, and programmability, becoming the "invisible guardian" of intelligent automotive electronic systems.

SG-8201CJA automotive grade crystal oscillator product features:

1. Ultra high precision and ultra-low jitter

SG-8201CJA adopts Epson's unique low-noise fractional N phase-locked loop technology, with a typical phase jitter value as low as 1.1 ps (@ 125MHz). In ADAS core sensors such as radar and LiDAR, it can ensure the integrity of signal acquisition and transmission, avoiding the risk of misjudgment caused by clock deviation. Its frequency accuracy has a tolerance of only ± 15 × 10 ⁻⁶ within the range of -40 ° C to+105 ° C, and it maintains stable output even in extreme environments, providing reliable support for key components such as new energy vehicle battery management systems (BMS).

2. Wide temperature range and vehicle grade certification

Supports working temperatures ranging from -40 ° C to+125 ° C, in compliance with AEC-Q100 * * automotive standards, suitable for harsh working conditions such as high temperature and severe cold in the engine compartment, ensuring stable operation of onboard cameras, Ethernet communication modules, and other devices around the clock.

3. programmability and flexible adaptation

The output frequency covers 1.2MHz to 170MHz and supports programming at any frequency. Developers can quickly adapt to different system requirements without changing hardware, significantly shortening the development cycle and helping car companies cope with the challenges of rapid iteration of intelligent functions.

4. Miniaturization and lightweight design

Adopting a 2.0 × 1.6mm ultra compact package, it provides a highly integrated solution for space limited components such as car cameras and LiDAR, while reducing the overall weight of the vehicle and indirectly improving energy efficiency performance.

SG-8201CJA automotive grade crystal oscillator application scenarios:

1. ADAS and autonomous driving

As the clock core of millimeter wave radar, LiDAR, and visual cameras, SG-8201CJA ensures the synchronization accuracy of sensor data and assists in the efficient operation of environmental perception and decision-making systems. For example, in automatic parking scenarios, its low jitter characteristics can avoid image transmission packet loss and improve obstacle recognition accuracy.

2. In vehicle communication and network

Provide high stability clock benchmarks for in car Ethernet and 5G-V2X modules, ensuring high-speed transmission of data inside and outside the vehicle, supporting OTA upgrades, real-time navigation, and other networking functions.

3. Intelligent cockpit and entertainment system

In scenarios such as multi screen interaction and voice interaction, precise clock signals can eliminate the problem of audio and visual asynchrony and enhance user experience.

4. Electrification and Energy Management

In the Battery Management System (BMS), high-precision clock signals assist in monitoring and balancing the battery cell status, extending the range; Simultaneously providing a timing reference for the motor controller to optimize driving efficiency.
