EXTERNAL INTERFACE
The DE6003 transceiver has a simple external interface, with
all but three interface connections having CMOS compatible
switching levels: some inputs have pull-down or pull-up resistors.
The DE6003 connection list, Table 2, is followed by a description
of each of the external connections in pin number order.
On power up, the DE6003 transceiver should have its control
inputs set to receive with the power amplifier off. On power
switch-on, a channel within the 101 channels is selected by the
value that is on the select data inputs SD(6:0); the correct channel
should be loaded by placing the channel number on the select
data inputs and strobing the channel data in with LOADB.
The antenna select input (ANTSEL) is used to switch
between the two antenna ports; this input should be set to
antenna 1 for transmit and only switched when the transceiver
is in receive mode for antenna diversity selection.
The data input (TXD) has data applied in simple non-return
to zero (NRZ) format with the maximum consecutive ‘1’s or ‘0’s
limited to 16. Receive data (RXD) is demodulated and output in
NRZ format with no clock extracted. The RXD output is
designed to drive a high impedance CMOS input with a
maximum load capacitance of 6pF. Loads in excess of 6pF will
extend the negative edge time of the output data resulting in
pulse stretching.
