Overview

CH9126 is a network time giving IC based on SNTP protocol, which can mainly solve the problem of MCU and other embedded devices' time synchronization problem. CH9126 has two work modes: (1) work as a SNTP Client, receive time from a SNTP Server and output through serial port; (2) work as a SNTP Server, use pulse and serial port data as reference time, give time to SNTP Clients. CH9126 also has a data transparent channel inside, which can provides serial data and network data 's two-way penetrate transparent.

Features
