APPLICATIONS INFORMATION

PROTOTYPE INTERFACE BOARD

The ADIS16488/PCBZ includes one ADIS16488AMLZ, one

interface printed circuit board (PCB), and four M2 × 0.4 × 18 mm

machine screws. The interface PCB provides four holes for

ADIS16488AMLZ attachment and four larger holes for

attaching the interface PCB to another surface. The

ADIS16488AMLZ 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 27 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 28 and Figure 29 provide the mechanical design

information used for the ADIS16488/PCBZ. Use these

figures when implementing a connector-down approach,

where the mating connector and the ADIS16488AMLZ are on

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

the mounting holes shown in Figure 28 as a guide in designing

the bulkhead mounting system and use Figure 29 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.
