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 Am79C988A 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 fullduplex mode.

The QuIET Am79C988A interfaces directly with the Pseudo AUI (PAUI™) ports on the IMR2 (Am79C983A) device and can also be connected to standard AUI ports. Command and status data are exchanged with the IMR2 device via a serial management interface. Port switching can be easily implemented with the IMR2/QuIET chipset to move individual  orts between multiple Ethernet segments under software control.

For application examples on building fully-managed repeaters using the QuIET and IMR2 Am79C988A, refer to AMD's
IMR2 Technical Manual (PID 19898A).

The QuIET chip is packaged in a 44-pin plastic leaded chip carrier (PLCC). Am79C988A is fabricated in CMOS technology and requires a single 5-V supply.
