GSY-GM-220-III L2 High Quality GNSS Precision Timing Module

Introduction

GSY-GM-220-III L2 High Quality GNSS Precision Timing Module is based on a dual-system multi-frequency high-performance soc chip with independent intellectual property rights, which can support two frequency points, BDS B1 and GPS L1. The GSY-GM-220-III L2 is small in size, with SMT pads, and supports the automatic integration of standard pick and placement reflow soldering. It is especially suitable for applications such as telecom base station timing, power timing, and LAN synchronization.
