ML145428
Asynchronous–to–Synchronous and Synchronous–to– Asynchronous Converter
Legacy Device: Motorola MC145428
The ML145428 Data Set Interface provides asynchronous-to-synchronous and synchronous-to-asynchronous data conversion. It is ideally suited for voice/data digital telesets supplying an EIA-232 compatible data port into a synchronous transmission link. Other applications include: data multiplexers, concentrators, data-only switching, and PBX-based local area networks. This low-power CMOS device directly interfaces with either the 64 kbps or 8kbps channel of Motorola’s MC145422 and MC145426 Universal Digital Loop Transceivers (UDLTs), as well as the MC145421 and MC145425 Second Generation Universal Digital Loop Transceivers (UDLT II). Provides the Interface Between Asynchronous Data Ports and Synchronous Transmission Lines Up to 128 kbps Asynchronous Data Rate Operation Up to 2.1 Mbps Synchronous Data Rate Operation On-Board Bit Rate Clock Generator with Pin Selectable Bit Rates of 300, 1200, 1400, 4800, 9600, 19200 and 38400 bps or an Externally Supplied 16 Times Bit Rate Clock Accepts Asynchronous Data Words of 8 or 9 Bits in Length False Start Detection Provided Automatic Sync Insertion and Checking Single 5 V Power Supply Low Power Consumption of 5 mW Typical Application Notes AN943 and AN946 Operating Temperature Range TA = –40º to +85ºC.
