MOTOROLA SEMICONDUCTOR TECHNICAL DATA Technical Summary Dual Data Link Controller This technical summary gives a brief overview of the MC145488 Dual Data Link Controller. The MC145488 is a two–channel ISDN LAPD controller with an on–chip direct memory access (DMA) controller. It is intended for ISDN terminal and switch applications where one or two channels of data will use HDLC–type protocols. The DDLC can also be used in local area, wide area network, and bridge router applications. Each serial interface can be clocked at data rates up to 10 Mbps. The DDLC can operate with microprocessors using clock frequencies up to 20.5 MHz. www.DataSheet4U.com The DDLC is ideally suited for use with the MC145474 S/T–Transceiver.
