Contextual Info: SECTION 2 MODEM REFERENCE PLATFORM 2.1 REFERENCE PLATFORM BLOCK DIAGRAMS The purpose of this section is to describe a typical V.34 modem application which uses the 68DP356. Figure 2-1 shows the major blocks required to build a stand-alone, RS232 “box type” modem. The major blocks required consist of the 68DP356 single chip modem controller/datapump, the memory required to implement the user specific modem controller solution the datapump is totally contained on-chip , the ST7544 modem analog interface chip,
