Assembly
On the next pages are some figures to assist the customer in
designing his printed circuit board (PCB). Figure 13 shows the
mechanical dimensions of the PAROLI transmitter and receiver
modules and Figures 14 to 16 give the dimensions of the holes
and solder pads on a customer PCB that are necessary to
mount the modules on this PCB. Keeping the tolerances for the
PCB given in Figures 14 to 16 is required to properly attach the
PAROLI transmitter and receiver module to the PCB.
Attachment to the customer PCB should be done with four M2
screws torqued to 0.25 Nm + 0.05 Nm (see Figure 13, cross
section B-B). The screw length
a
should be 3 to 4 mm plus the
thickness
b
of the customer PCB.
Special care must be taken to remove residues from the solder-
ing and washing process which can impact the mechanical
function. Avoid the use of aggressive organic solvents like
ketones, ethers, etc. Consult the supplier of the PAROLI mod-
ules and the supplier of the solder paste and flux for recom-
mended cleaning solvents.
The following common cleaning solvents will not affect the
module: deionized water, ethanol, and isopropyl alcohol. Air-dry-
ing is recommended to a maximum temperature of 140
°
C. Do
not use ultrasonics.
During soldering, heat must be applied to the leads only, to
ensure that the case temperature never exceeds 140
°
C. The
module must be mounted with a hot-air or hot-bar soldering
process using a SnPb solder type, e.g. Sn62Pb36Ag2, in accor-
dance with ISO 9435.

CLK_SEL
LVCMOS In Input Clocking Mode Select
High=strobe mode
Low=SCI mode
This input has an internal pull-
up resistor. When left open,
strobe mode is active.

OE
LVCMOS In High=enable LVDS outputs
Low=set LVDS outputs (data
and clock) to static low level. In-
ternal pull-up pulls to high level
when input is left open
