7. DESIGN CONSIDERATIONS
The CS8952 is a mixed-signal device containing
the high-speed digital and analog circuits required
to implement Fast Ethernet communication. It is
important the designer adhere to the following
guidelines and recommendations for proper and re-
liable operation of the CS8952. These guidelines
will also benefit the design with good EMC perfor-
mance.
7.1
Twisted Pair Interface
The recommended connection of the twisted-pair
interface is shown if Figure 6. The unused cable
pairs are terminated to increase the common-mode
performance. Common-mode performance is also
improved by connecting the center taps of the RX
and TX input circuits to the DC-isolated ground
plane. The 0.01 F capacitor C1 must provide 2 kV
(1,500 Vrms for 60 seconds) of isolation to meet
802.3 requirements. If a shielded RJ45 connector is
used (recommended), the shield should be connect-
ed to chassis ground.
7.2
100BASE-FX Interface
Figure 7 shows the recommended connection for a
100BASE-FX interface to a Hewlett-Packard
HFBR-5103 fiber transceiver. Termination circuit-
ry may need to be revised for other fiber transceiv-
ers. The FX Drive bit in the Loopback, Bypass, and
Receiver Error Mask Register (address 18h) may
be used to tailor the PECL interface for 50
or
150
loads.
0
Jabber Enable
Read/Write 1
When set, the jabber function is enabled. When
clear, and if the CS8952 is in 10BASE-T full-duplex
or 10BASE-T ENDEC loopback mode, the jabber
function is disabled.
Note: When the National Compatibility Mode bit (bit
7) is set, the Jabber function may also be disabled
for 10BASE-T half-duplex, although this is not rec-
ommended.
