GENERAL DESCRIPTION
The Am79C988A Quad Integrated Ethernet Transceiver
(QuIET) device consists of four independent 10BASE-T
transceivers which are compliant with the IEEE 802.3
Section 14 (
Medium Attachment Unit for 10BASE-T
Cabling
) standard. When combined with AMD's
Integrated Multiport Repeater 2 (IMR2) chip, the
QuIET device provides a system-level solution to
designing a managed 10BASE-T repeater.
The QuIET device includes on-chip filtering for both
transmit and receive functions, thus eliminating the
need for external filters. On-chip filtering meets IEEE
802.3 (Section 14.3) electrical requirements. The
QuIET device provides automatic polarity detection and
correction and can operate in either normal or full-
duplex mode.
The QuIET device interfaces directly with the Pseudo
AUI (PAUI) ports on the IMR2 (Am79C983A) device
and can also be connected to standard AUI ports. Com-
mand and status data are exchanged with the IMR2
device via a serial management interface. Port switch-
ing can be easily implemented with the IMR2/QuIET
chipset to move individual ports between multiple Ether-
net segments under software control.
For application examples on building fully-managed
repeaters using the QuIET and IMR2 devices, refer to
AMD’s
IMR2 Technical Manual
(PID 19898A).
The QuIET chip is packaged in a 44-pin plastic leaded
chip carrier (PLCC). The device is fabricated in CMOS
technology and requires a single 5-V supply.
