EPSON high stability digital real-time clock module RX-8803LC supporting I2C bus interface assists in the development of time sensitive network applications

With the development of current distributed computing systems, the concept of time sensitive networks has been developed. Time sensitive networks not only require precise stability of clock signals, but also require data exchange between different computing chips. For the basic components supporting the construction of time sensitive networks, the digital real-time clock module needs to have two characteristics: high frequency stability as much as possible and interconnection with multiple computing chip networks. EPSON introduces a digital real-time clock module with two characteristics, which can be widely used in industrial distributed computing, vehicle Internet and other applications.

EPSON, as a professional manufacturer providing clock solutions for application customers, fully understands the requirements of application scenarios and has launched the RX-8803LC digital real-time clock module for real-time clock design in multi computing chip application scenarios. The frequency output characteristics of this product are stable, and the internal frequency changes caused by temperature changes are corrected through digital AD acquisition. At the same time, it supports the I2C bus and can interact with multiple external chips for data exchange, better supporting the design and development of time sensitive network products.

Within a wide temperature range of -40 ° C to+85 ° C, the frequency tolerance can reach+3.4x10-6, and the frequency characteristics are stable and reliable

For time sensitive networks, the stability and accuracy of clock signals are a rigid requirement in product design. RX-8803LC has launched four sub models: UA, UB, UC, and AA. The difference between each sub model lies in its frequency stability. Design users can choose the appropriate model according to their own needs. Among them, RX-8803LC UA has a frequency tolerance of+3.4 x10-6 in a wide temperature range of -40 ℃ to+85 ℃, which has good stability and meets various high reliability application scenarios.

Support I2C bus communication and achieve interconnection of multiple computing chips

In time sensitive network applications, clock signals require synchronous communication, so digital real-time clock modules need to be involved in interconnection communication. The RX-8803LC supports the I2C bus interface, which adopts a bidirectional, half duplex serial communication protocol and supports multi chip interconnection communication. It can be applied in distributed computing application scenarios, helping design users establish strict time standards between multiple computing chips and providing customers with high-quality technical support.

Rich built-in functions, supporting GPS signal synchronization applications

The RX-8803LC has rich built-in functions, and the internal registers of the module can be configured through the communication bus. At the same time, various timer interrupts, alarm interrupts, and external pin interrupts can also be set. The product provides complete and open technical information, and users have the design leadership over this module. In addition, the RX-8803LC also supports time synchronization of second pulse signals (1PPS) and GPS signal synchronization, which is very valuable for time sensitive network applications that require external time synchronization. It provides component level technical preparation.
