DS2187中文资料接收线路接口数据手册ADI规格书

描述 Description

The DS2187 T1/CEPT receive line interface chip interfaces user equipment to North American (T1 1.544MHz) and European (CEPT 2.048MHz) primary rate communication networks. The device extracts clock and data from twisted pair or coax transmission media and eliminates expensive discrete components and/or manual tuning required in existing T1 and CEPT line termination electronics. Application areas include DACS, CSU, CPE, channel banks, and PABX-to-computer interfaces such as DMI and CPI.

特性 Features
