Synopsys 640-pin Generic Device Adapter manual P5V, ADJVCC1, ADJVCC2, M5V, FANP12V

The ModelSource 640-pin Adapter Chapter 2: Building the Daughterboard

❍J4-FP5–J4-FP8 (FANP12V), if used

❍DUT signal used for DUT clock

●You can connect to any of the available power supplies listed in Table 1. Do not interconnect different power supplies.

Table 1: Available Power Supplies

Pins	Signal	Power Supply
J2-AP5–J2-AP8	P5V	+5V DC, 6A max
J4-AP5–J4-AP8
J2-AP1–J2-AP4	ADJVCC1	+3-5V DC, 6A max
J4-AP1–J4-AP4	ADJVCC2	+3-5V DC, 6A max
J4-FP1–J4-FP4	M5V	-5.2V DC, 400mA max
J2-FP5–J2-FP8	P12V	+12V DC, 400mA max
J4-FP5–J4-FP8	FANP12V	+12V DC, 400mA max (for
		fan/heat sink only)

●For bypass/decoupling capacitors, follow the DUT manufacturer’s recommendations, if provided; otherwise, use the following guidelines:

❍For each supply of P5V, ADJVCC1 or ADJVCC2, provide 47∝F, 16V tantalum (use two of these, if space permits).

❍For each supply of P12V, M5V, provide 10∝F, 16V tantalum.

❍For bypass, for every 25 signal pins, place a pair of 0.1∝F and 0.01∝F high frequency X7R or NPO capacitors directly underneath the device, if possible, or around the perimeter of the device.
