ATA6565

To switch the device to Normal operating mode, set the

STBY pin to low and the TXD pin to high (see Table 1-1

and Figure 1-2). The STBY pin provides a pull-up

resistor to VCC, thus ensuring a defined level if the pin

is open.

1.1.1

NORMAL MODE

Alow level on the STBY pin, together with a high level on

the TXD pin, selects the Normal mode. In this mode, the

transceiver is able to transmit and receive data via the

CANH and CANL bus lines (see the Block Diagram).

The output driver stage is active and drives data from the

TXD input to the CAN bus. The High-Speed Comparator

(HSC) converts the analog data on the bus lines into

digital data, which is output to the RXD pin. The bus bias-

ing is set to V_VCC/2 and the undervoltage monitoring of

Please note that the device cannot enter Normal mode

as long as TXD is at ground level.

The switching into Normal mode is depicted in

Figure 1-2.

V_VCCis active.

The slope of the output signals on the bus lines is con-

trolled and optimized in a way that ensures the lowest

possible Electromagnetic Emission (EME).
