Features

  • Two-chip, single-lane PCI-Express soft modem solution with an integrated interface that supports
    the PCI-Express revision 1.1 standard:
    — SV92EX host interface in a 32-pin MLCC                    — CSP1040 DAA in a 20-pin TSSOP
  • Data mode capabilities:
    — ITU-T ™ V.92*: 56000 bits/s—28000 bits/s               — ITU-T V.90*: 56000 bits/s—28000 bits/s                     — ITU-T V.34: 33600 bits/s—2400 bits/s                        — V.32bis and fallbacks
    — V.44, V.42, V.42 bis, and MNP ™
         Class 5 data compression
    — High compression throughput due to
         parallel access directly to the host PC
  • FAX mode capabilities:
    — ITU-T T.31 class 1 FAX
    — ITU-T V.17: 14400 bits/s, 12000 bits/s,
         9600 bits/s, 7200 bits/s (TCM)
    — ITU-T V.29: 9600 bits/s, 7200 bits/s (QAM)
    — ITU-T V.27ter: 4800 bits/s, 2400 bits/s (DPSK)
    — ITU-T V.21 Channel 2: 300 bits/s (FSK)
  • CSP1040:
    — System-powered
    — Proprietary isolation barrier
    — Programmable event detect for caller-ID
         reception and power ring detection
    — Programmable pulse shaping and
         spark quench
    — Programmable dc-impedance termination
         for country-specific VI templates
    — Programmable ac-impedance termination
         for return-loss matching                                                 — Programmable ringer-impedance emulation
  • Hardware support for pulse dialing for accurate
    make/break timing
  • Wake-on-ring and caller ID support
  • Common driver across multiple platforms

Benefits

  • CSP1040 device is LSI’s third-generation silicon DAA:
    — Reduces the number of components and board  
         area required to implement a full-featured modem, 
         while achieving compliance with worldwide 
         regulatory requirements 
  • Digital link also provides power to the CSP1040, allowing full operation on marginal phone lines.          — This digital link also provides power to the  
         CSP1040, allowing full operation on marginal 
          phone lines
  • CSP1040 includes hardware support for detecting line-in-use status, overcurrent, polarity reversals, caller ID, and ringing, without the need for additional external circuitry                                                                                    — Allows for full-featured modem designs without
         increased bill-of-materials or board space
