Integrated Multiport Repeater Plus™ (IMR+™)

Advanced Micro Devices 

AMD

PRELIMINARY

For application examples on building a fully managed

repeater using the IMR+ and HIMIB devices, refer to

AMD’s IEEE 802.3 Repeater Technical Manual

(PID#17314A) and the ISA-HUBTM User Manual

(PID # 17642A).

The device is fabricated in CMOS technology and re-

quires a single +5 V supply.
