MX97102UC

MX97102 ISDN S/T CONTROLLER FEATURES Pin-to-Pin and Register-to-Register compatible with Siemens 2186 Full duplex 2B+D ISDN S/T Transceiver according to CCITT I.430 GCI digital interface 3 types of 8-bit CPU interface Receive timing recovery with adaptively switched thresholds E-channel Monitoring Programmable SDS1,SDS2 D-channel access control LAPD(HDLC) support with FIFO(2x64) buffers Activation/Deactivation Multiframing with S and Q bit access CPU access to B and IC channels Watchdog timer Package types : P-LCC-44, P-LQFP-64 GENERAL DESCRIPTIONS MX97102 implements the 4-wire S/T interface used to link voice/data terminals to an ISDN. It is designed for the user site of the ISDN-basic access, two 64kbit/s B channels and a 16kbit/s D channel. MX97102 can be mainly divided into three portions according to their interfaces. Except these three interface functions, it also provides the LAPD controller which handles the HDLC packets of the ISDN D-channel for the associated microprocessor. The first, S/T interface controller, provides all electrical and logical functions of the S/T interface, such as S/T transceiver, activation/deactivation, timing recovery, multiframe S and Q channels, and D-channel access and priority control for communicating with remote equipments. The Second is the microprocessor interface controller which offers the registers compatible with Siemens PSB2186, provides three types of microprocessor interface, such as Motorola bus m...
