µPD98402A
LOCAL ATM SONET FRAMER
The µPD98402A is one of the ATM-LAN LSIs and incorporates the TC sublayer function in the SONET/SDH-
based 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.
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 interface
• Provided with registers for writing/reading overhead information
SOH (section overhead): C1 (1st to 3rd) bytes, F1 byte
LOH (line overhead): K2 byte
POH (pass overhead): F2 byte, C2 byte
• CMOS process
• +5 V single power supply
