MC68194
Carrier Band Modem (CBM)
The bipolar LSI MC68194 Carrier Band Modem (CBM) when
combined with the MC68824 Token Bus Controller provides an IEEE
802.4 single channel, phase–coherent carrier band Local Area
Network (LAN) connection. The CBM performs the Physical Layer
function including symbol encoding/decoding, signal transmission
and reception, and physical management. Features include:
• Implements IEEE 802.4 single channel, phase–coherent Frequency
Shift Keying (FSK) physical layer including receiver blanking.
• Provides physical layer management including local loopback mode,
transmitter enable, and reset.
• Supports data rates from 1 to 10 Mbps. IEEE 802.4 standard uses 5
or 10 Mbps.
• Interfaces via standard serial interface to MC68824 Token Bus
Controller.
• Crystal controlled transmit clock.
• Recovery of clocked data through phase–locked loop.
• RC controlled Jabber Inhibit Timer.
• Single +5.0 volt power supply.
• Available in 52–lead Cerquad package.
