UPD98402A Datasheet Local Atm Sonet Framer

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD98402A LOCAL ATM SONET FRAMER The µPD98402A is one of the ATM-LAN LSIs and incorporates the TC sublayer function in the SONET/SDHbased physical layer of the ATM protocol. The main functions of the µPD98402A include a transmit function for mapping ATM cells received from the ATM layer onto the payload block of the SONET STS-3c/SDH STM-1 frame and sending them to PMD (Physical Media Dependent) in the physical layer, and a receive function for separating the overhead block and ATM cells from the data string received from the PMD sublayer and sending the ATM cells to the ATM layer. Futhermore, the µPD98402A is compliant with the ATM Forum UNI Recommendations.

Key Features

  • Provision of TC sublayer function of ATM protocol physical layer.
  • Support of SONET STS-3c frame/SDH STM-1 frame format.
  • Provision of stop mode for cell scramble/descramble and frame scramble/descramble.
  • Disposal/transitory selection of unassigned cells is possible.
  • Compliant with UTOPIA interface.
  • Incorporation of internal loopback function at PMD and ATM layer turns.
  • PMD interface 155.52 Mbps serial interface 19.44 MHz parallel in.
