Desktop Transceiver SFX-TAP4_2/C, V0.1, Technical Description
9
4 Hardware Components
4.1 Voltage Supply
Die voltage supply of the Desktop Transceiver SFX-TAP4/C (SFX-TAP2/C) is obtained by using
the wall power supply. Connect it to the PWR plug of the Transceiver.
4.2 PIP Complex
Count of I/O:
32
Formatting:
4 x 8, 2 x 16
Input voltage range:
0 V – 5,0 V
Output voltage range:
1.8 – 4.5 V
For the PIP unit, there are no handshake signals available. The user must ensure a safe data
transmission.
The output driver of the PIP‘s are activatable group-wise which means 8 or 16 Bit each can be
in tristate or active mode.
The PIP complex is designed with the same driver circuitries as for TAPs. For further
information refer to chapter 4.8 and [2].
4.3 Analog IO Signals
Analog signals can be provided ore measured on pin 13 and 15 of the AUX connector. Signal
generation and Measuring are based on 10-bit converter technique. The voltage range covers 0
and 4.096 V with a maximum rating of - 0.3 to +5.0 V.
The analog output serves an inline resistor of 1 kOhms.
4.4 Digital IO Signals
The AUX connector has 3 general purpose digital I/O signals on pins 7, 9, and 11. All of them
have a 22 Ohm in-line resistor. The connected logic IC is PCA9555. Input voltage range is -0.5
V to 6 V, following is the data sheet of that IC type.
