BOARD LAYOUT
1. The SP508 Evaluation board takes ad-
vantage of the products PCB friendly flow
through pinout in its design as shown in
Figure 1.
2. The SP508 Evaluation Board has been
designed to easily and conveniently provide
access to all inputs and outputs under test.
3. Figure 1 is a block diagram of the evalu-
ation board showing the layout of the SP508
Evaluation Board. The block diagram shows
the location of the driver and receiver ac-
cess points as well as the DIP switches, V
CC
,
GND and the DB-25 Connector.
4. I/O Pinouts
The SP508 Evaluation Board has been de-
signed to easily and conveniently provide
access to all inputs and outputs to the device
under test. Position the Board with the DB-
25 connector at the top and the Dip switches
at the bottom. From this orientation , all
driver inputs and outputs are on the right-
hand side and all receiver inputs and out-
puts are on the left-hand side eof the Board.
4.1. Each Driver has probe points for the
input and outputs. There is a ground buss to
the right of the drive outputs for the addition
of loads to the driver outputs and to jumper
the V.35 that is associated with the SD, TT,
and ST driver. Each V.35 driver has a
separate ground for the V.35 termination
network internal to the device.
4.2. Each Receiver has probe points for the
inputs and outputs. there is a ground buss
to the left of the receiver outputs and a
separate pin for the V.10 termination ground.
5. At the bottom of the board is a series of
six(6) DIP switches. The DIP switch on the
far left is for D_LATCH and TERM_OFF.
Each driver and receiver has its own indi-
vidual enable pin. The DIP switches to
control the enable pins are located as the
top center bank of switches for the driver and
the middle center bank of switches for the
receiver. The bottom center set of DIP
switches is for the 3 bit decoder and the
loopback control pin. The right hand DIP
switches allow the user to tie the ST driver
outputs to the TxC receiver inputs and the
RRC driver outputs to the RRT receiver
inputs.
6. Also located on the SP508 evaluation
board are the four 10uf charge pump capaci-
tors, a 10uf bypass capacitor for V
CC
and a
50
termination resistor.
7. Table 1 shows the pinout of the DB-25
connector used to connect to a communica-
tion analyzer such as the TTC Firebird 6000.
