    ATM 25.6 Mbps Multi-PHY Device

    The Fujitsu FireBurst? 25 MB86688B ATM 25.6Mbps Multi-PHY Device is a highly integrated multiple port interface between the magnetics and the ATM Adaptation Layer of an ATM system. Implementing six UNI ports on a single device significantly reduces the cost per port. Each of the six UNI ports provides framing and transceiver functions according to the ATM Forum 25.6Mbps Physical Layer Specification. The device has a 16 bit UTOPIA Level 2 compliant ATM cell interface that can operate at up to 52MHz. Six 25.6Mbps cell streams are concentrated onto a single Multi-PHY UTOPIA interface under the control of an ATM Layer device. Mixed-signal technology is used to implement all the Physical Layer circuitry at each UNI port. All Physical Media Dependent (PMD) functions, including line drivers, equalisation and clock recovery are included in each transceiver block. Transmission Convergence (TC) functions are performed by each 25.6Mbps framer block. The FireBurst? 25 is designed for use in any UTOPIA Level 2 based system including 622Mbps switches and stand alone concentrators.
