APPLICATIONS INFORMATION

PROTOTYPE INTERFACE BOARD

The ADIS16480/PCBZ includes one ADIS16480AMLZ,

one interface printed circuit board (PCB), and four M2 × 0.4 ×

18 mm machine screws. The interface PCB provides four

holes for ADIS16480AMLZ attachment and four larger holes

for attaching the interface PCB to another surface. The

ADIS16480AMLZ attachment holes are pre-tapped for M2 ×

0.4 mm machine screws and the four larger holes, located in

each corner, support attachment with M2.5 or #4 machine

screws. J1 is a dual row, 2 mm (pitch) connector that works with

a number of ribbon cable systems, including 3M Part Number

152212-0100-GB (ribbon crimp connector) and 3M Part Number

3625/12 (ribbon cable). Note that J1 has 16 pads but currently

uses a 12-pin connector. The extra pins accommodate future

evaluation system plans.

Figure 28 provides the pin assignments for J1. The pin

descriptions match those listed in Table 5. The C1 and C2

locations provide solder pads for extra capacitors, which

can provide additional filtering for start-up transients and

supply noise.

INSTALLATION TIPS

Figure 29 and Figure 30 provide the mechanical design

information used for the ADIS16480/PCBZ. Use these

figures when implementing a connector-down approach,

where the mating connector and the ADIS16480AMLZ are on

the same surface. When designing a connector-up system, use

the mounting holes shown in Figure 29 as a guide in designing

the bulkhead mounting system and use Figure 30 as a guide in

developing the mating connector interface on a flexible circuit

or other connector system. The suggested torque setting for the

attachment hardware is 40 inch-ounces, or 0.2825 N-m.
