Data Sheet
22.9
The INCA-D provides onchip receiver and transmitter circuitries which allows to connect
the INCA-D directly to the USB bus. The USB driver circuitry is shown in Figure 22-21.
The USB transceiver is capable of transmitting and receiving serial date at full speed (12
MBits/s) data rate. Transceiver and receiver can be separately disabled for power down
mode operation. A single ended zero error condition (D+ and D- both at low level) can
be detected.

Figure 22-21 USB Onchip Driver Circuitry
The USB driver circuitry is a differential output driver which drives the USB data signal
onto the cable of the USB bus. The static output swing of the transmitter is in low state
below 0.3 V with a 1.5 k load to 3.6 V and in high state above 2.8 V with a 15 k load
to V
operation (control bits RPWD and TPWD). High impedance is also required to isolate the
port from devices that are connected but powered down. The driver tolerates exposure
to waveforms as specified in chapter 7.1 of the USB V1.1 Specification..
For a full speed USB connection the impedance of the USB driver must be between 29
or falling (monotonic), and are well matched to minimize RFI emissions and signal skew.
Figure 22-21 shows how the full speed driver is realized using two identical CMOS
buffers. Figure 22-22 shows the full speed driver signal waveforms.
