IP568x

IP568x 56K V.90 Modem Single Chip Features „ Data mode capabilities: − ITU-T V.90 − ITU-T V.34 − ITU-T V.32bis, V.32 − ITU-T V.22bis,V.22 − ITU-T V.23, V.21 − Bell 212 − Bell 103 „ FAX mode capabilities: General Description The Modem Chip IP568x is a highly integrated, low-cost, high performance, low-power, a full-function modem solution. IP568x implements V.90 to achieve Internet connection rates up to 56Kbps, supporting existing V.34 data mode, video-ready interface, Class 1 FAX, TAM (Telephone Answer Machine) and Speakerphone functions. IP568x’s I/O pins allow designer to easily control DAA or design modem for special application. IP568x is a µDSP-based chip designed specifically for modem application, and it performs high MIPS operations such as V.90, V.34 and V.32 modulation. IP568x provides a serial interface for connecting to codec. IP568x uses high quality design to optimize modem configuration for line condition and provide reliable connection with connection rate ranging from 300bps up to 56Kbps. IP568x is the best choice for designing a modem. 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 77 76 75 74 73 72 71 70 69 68 67 66 65 IP568x 128Pin LQFP System Block Diagram IP568x RS-232C Interface RS-232C Interface µDSP Preliminary, Specification subject to change without notice IP568x-DS-P05, Nov, 2002 Copyright@2002, IC ACE Corp. w w w . t a d h s a t e e . u 4 External Memory Inter...
