CCLK lines are also used to signal to an external controller certain internal activities of the transceiver. The receiver
is activated upon detection of RF energy during Sniff Mode
operation. The wake-up timer can also be configured to wake-up the
device in order to alert an external controller to perform specific tasks, as defined by the system designer.
8.10 TX/RX, Data Input/Output Pin
The transmit/receive (TX/RX) pin can be programmed to be either an input for RF transmissions, or an output for RF reception, or the
output of the RC oscillator signal, or the output of the recovered data from the CDR circuits, respectively.
In transmit mode, this pin is the digital data input to the AMIS-52150 RF transmit circuit. The digital data results in the On and Off
cycling of the output power amplifier (PA). The AMIS-52150 does not perform any protocol conversion on the data bit stream; it is
simply a serial bit stream. The state of the TX/RX pin either turns the output amplifier On (enabling RF transmission) or turns the output
amplifier Off (disabling RF transmission). The TX/RX input can be inverted which causes the state control of the RF output amplifier to
be inverted as well.
In receive mode, this pin is the digital data output from the AMIS-52150 receivers. The received data is recovered as a high/low (digital
ones and zeros) serial bit stream; the AMIS-52150 does not modify the received data protocol. The data output state due to the
presence of energy in the receiver can be programmed to be either a high level or a low level at the TX/RX pin. An external controller is
needed to decode the information in the recovered data bit stream.
When programmed to be an oscillator output, the TX/RX pin outputs the signal from the RC oscillator. This signal can be used to
monitor the frequency of the RC oscillator in order to trim the frequency to the desired value.
The TX/RX pin can be programmed to output the recovered data obtained from the clock and data recovery circuits. In this case, the
device must be programmed in the CDR mode. More information on CDR will be provided in a later section of this datasheet.
The functions of the TX/RX port are controlled by the values of the register settings, as shown in Table 18.
