UPD98402A Description
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...
