8.4.1 OOK Mode

Data at the D input is modulated with the carrier frequency set by the RF_SET value when the device is transmitting (MODE = VCC). See Section 8.3.1 section for more details. In receiving (MODE = GND), the device expects an OOK modulated signal at the A and B inputs. The data is demodulated and sent out via R pin. See Section 8.3.2 section for more details.

INPUTS OUTPUTS FUNCTION
F_SET MODE D A B
RF_SET (See Table 8-1) H H or Z Bias to VCM Bias to VCM Driver is actively biased to VCM on the bus
H L Oscillating Oscillating Bus actively driven at carrier frequency
L or Z X Z Z Driver disabled, device in receive mode

INPUTS OUTPUT FUNCTION
F_SET MODE Input R
RF_SET (See Table 8-1) L or Z Oscillating at F_SET and VID > VMAG_ZERO L Receive valid bus low
L or Z Oscillating at F_SET and VMAG_ONE < VID < VMAG_ZERO ? Receive invalid bus, output indeterminate
L or Z Oscillating at F_SET and VID < VMAG_ONE H Receive valid bus high
L or Z Z / not oscillating H Receive valid bus high
L or Z OPEN, SHORT, IDLE (VID = 0 V) H Failsafe high output
H X Z Receiver disabled, device in transmit mode
