1.0 General DescriptionThe DS92UT16isa flexible UTOPIAto LVDS Bridge device.
The LVDS Bridge transparently transportsthe UTOPIA bus
overa high speed LVDS serial link. The device includes
many reliability features suchasan optional 1:1 protection
and builtinbit error rate checking.
The parallel interfaceis user programmablefor maximum
flexibility. The user can choose between UTOPIA Level Level ATM layer (master)of PHY layer (slave). The UTOPIA-
LVDS Bridge supportsa special MPHY (multi-PHY layer)
operation mode. The MPHY operation supportsupto 248
standard UTOPIA Level2 PHY ports without adding external
circuitry.
The serial interface uses LVDS Serializer and Deserializer
technology. The 16:1bit serialization allows conveying the
full-duplex parallel bus over two differential transmission
pairs. This enables low cost backplanes and cables. Cable
transmission length canbeas long16 meters.
The serial link carries Flow control information (back pres-
sure)in both directions. The Bridge device applies back
pressureona per queue basis over the31 internal FIFO
queues.In addition,the serial link includesan OAM (Opera-
tions and Maintenance) channel that does not detract from
link performance.
There are many applications where the UTOPIA-LVDS
Bridge simplifies designs. Box-to-box connections can use
DS29UT16 devices across cables. Access multiplexor appli-
cations can use the devices acrossa PCB backplanefor
point-to-point and lightly loaded multidrop configurations.
