1. Introduction This document provides an overview of the functionalities supported by the Digital Cordless Module (MD-1562) with Vega-1 based DECT processor. 1.1 Product overview _ Features summary The table below provided a brief summary of the key features supported by the MD-1562_CLxx series. Platform Features Application (DECT/DECT 6.0) MD-1562 Base Physical dimension (mm) 5*33*50 Pin count 32 pins Wideband audio codec G.
2. Digital Cordless Module (MD-1562) description 2.1 Chipset platform The MD-1562 DECT module is based on a highly integrated chipset for DECT and DECT VoIP application. 2.2 Numbering system The customer model number system below provides basic information of model number assignment for customer to place the order; a label shows the model number would be labeled on each module delivered! Product Cat. （1~2） ） Customer code （5） ） Platform （3~4） ） Reserved Serial No.
2.3 Typical application 2.3.1 For base： The cordless base using the MD-1562 contains a base band section & a RF section. The antenna(s) will be located outside the module PCB area. To compose a base, the module will need the additionally hardware interface to support line interface、power supply、handset charger interface...
2.3.2 For data application： The MD-1562 for data application can be executed as a MD-1562 base, combined with one co-processor, which then by the control of the module able to send data back and forth using the up to 32 Kbits/s air interface. It is possible to establish a data link from up to five handsets to one base and routing the data via the UART interface. However, the UART interface has a limited transmission speed up to 115.2Kb/s baud rate.
