Product application direction:
Ultra-short wave and short wave frequency bands in special defense application fields, single-soldier handheld, backpack, vehicle-mounted, ship-mounted, and airborne radios. Wireless communication radios have certain requirements for the accuracy of carrier frequency in actual use, but they should be used for a long time. The carrier frequency will produce frequency deviation due to the aging of the internal reference source crystal oscillator. When a certain deviation is reached, it will affect the normal communication function. When the radio communication network is established, synchronization will be implemented frequently, and the synchronization process will be frequent. The time-controlled product uses the 1pps signal of Beidou or GPS to effectively solve the problems caused by the communication carrier frequency deviation and overcome the dependence of the crystal oscillator on the aging index; the synchronization timestamp (PPS) retention function reduces the system overhead of synchronization within the radio service time slot, which is beneficial to the network synchronization maintenance of orthogonal networking, and is beneficial to the network synchronization of the radio in the silent mode, improving the anti-interference and anti-temptation capabilities of wireless communication, while also reducing the frequency of frequent transmission and reception of synchronization signals between radio networks and reducing the power consumption of the radio.
