Changed the bottom view package dimension for 32-QFN package.

3/9/2010
In Section 6.6, deleted “or the output signal at TXAP and TXAN pass
through a multiplexer, which selects the inputs to the ADC. In normal
operation, RXAP/RXAN are selected. In analog loopback mode,
TXAP/TXAM are selected”.
Added the schematic in Section 10.
At the beginning of Appendix A, added “with a 600
termination. With
other terminations the values will be different.”.
In Appendix A, added “This is nearly always the case for applications
using both transmit drivers since the required transformers are dry
types for most applications outside the U.S.”.
In Appendix A, added “The R3 resistors will be much larger than for the
cane when only a single transmitter is used since the impedance
needed to cancel the transmit signal in the receiver is not supplied by
two R3 resistors in parallel instead of only one. This means the
resistors will be approximately twice the ratio values in the previous
case.”
In Appendix A, deleted “When using a wet transformer design as in
Figure 16, the only difference is that the blocking capacitor, Cblock, is
removed. All other equations still hold true.”.
At the end of Appendix A, deleted “In this definition the worst-case THL
from the transmit pins to the Receive pins is 10.8 dB. An insertion loss
of 7 dB is assumed accounting for losses due to switch, bridge and
transformer.”.
