Pin Number
Function
Doc1:
Connections to the Rx Level Measurement Circuitry. A capacitor should be connected from
each pin to V
SS
.
Doc2:
BT:
A logic level to select the modem ‘BT’ (the ratio of the Tx Filter's -3dB frequency to the Bit-
Rate). A logic “1” sets the modem to a BT of 0.5, a logic “0” to a BT of 0.3.
Tx Out:
The Tx signal output from the FX489 GMSK Modem.
Tx Enable:
A logic “1” applied to this input enables the transmit data path through the Tx Filter to
the “Tx Out pin”. A logic “0” will put the “Tx Out” pin to V
BIAS
via a high impedance.
Tx PS:
A logic “1” applied to this input will powersave all transmit circuits except for the Tx Clock.
Tx Data:
The logic level input for the data to be transmitted. This data should be synchronous
with the “Tx Clock”.
Rx Data:
A logic level output carrying the received data, synchronous with the “Rx Clock”.
Rx Clock:
A logic level clock output at the received data bit-rate.
Tx Clock:
A logic level clock output at the transmit-data rate.
Rx S/N:
A logic level output which may be used as an indication of the quality of the received
signal.
V
:
Positive supply rail. A single +5 volt power supply is required. Levels and voltages within this
modem are dependent upon this supply. This pin should be decoupled to V
SS
by a capacitor
mounted close to the pin.
