The CC61130 GPS synchronized clock module is designed for digital broadcasting and cluster communications system. 1. Introduction

       CC61130 GPS synchronized clock module is a high precision, fast GPS locking. The CC61130 GPS synchronized clock module is designed for digital broadcasting and cluster communications system. The module using GPS technology and tame technology lock the internal crystal oscillator (TCXO) frequency to precision GPS time signal, providing high-precision time and frequency signals.

       CC61130 GPS synchronized clock module as time and frequency device is designed by our company. The advantages of the device is that as frequency locked fast, highly accurate, stabilize, reliability, easy system integration, etc. The CC61130  GPS synchronized clock module can be widely used in radio and television, cluster communication, time and frequency synchronization, and other fields.
