MAX5488 Evaluation Kit

Volatile/Nonvolatile Data Transfer

In the Channel A group box, copy the active tap value

to nonvolatile memory by clicking the Save active ?

NV button. As confirmation, the Command History

window shows SPI sequence 0x21.

In the Channel B group box, copy the active tap value

to nonvolatile memory by clicking the Save active ?

NV button. As confirmation, the Command History

window shows SPI sequence 0x22.

To copy both of the active tap values to nonvolatile

memory, click the Copy Both Wiper Registers to NV

Registers button. As confirmation, the Command

History window shows SPI sequence 0x23.

In the Channel A group box, copy the active tap value

to nonvolatile memory by clicking the Load NV ? active

button. As confirmation, the Command History window

shows SPI sequence 0x31.

In the Channel B group box, copy the active tap value

to nonvolatile memory by clicking the Load NV ?

active button. As confirmation, the Command History

window shows SPI sequence 0x32.

To copy both of the active tap values to nonvolatile

memory, click the Copy Both NV Registers to Wiper

Registers button. As confirmation, the Command

History window shows SPI sequence 0x33.

Keyboard Navigation

When you type on the keyboard, the system must know

which control should receive the keys. Press the TAB

key to move the keyboard’s focus from one control to

the next. The focused control is indicated by a dotted

outline. SHIFT+TAB moves the focus to the previously

focused control. Buttons respond to the keyboard’s

SPACE bar. Some controls respond to the keyboard’s

UP and DOWN arrow keys. Activate the program ’s

menu bar by pressing the F10 key, and then press the

letter of the menu item you want. Most menu items have

one letter underlined, indicating their shortcut key.

Detailed Description of Hardware

Evaluating the MAX5487 or MAX5489

The MAX5487 and MAX5489 are similar to the

MAX5488, but with a different end-to-end resistance.

To evaluate the MAX5487 or MAX5489, order a free

sample of the MAX5487ETE#G16 (refer to the

MAX5487/MAX5488/MAX5489 IC data sheet).

External User-Supplied SPI Interface

The EV kit may be modified for use with an external,

user-supplied SPI interface. First, with power off and

USB disconnected, flip the board over and cut the

traces that are on the back of the board, underneath

location J2. Install a standard dual-row header, and

connect a ribbon cable to the user-supplied SPI.

Using an External Power Supply

The EV kit may be used with an external, user-supplied

2.7V to 5.25V power supply. First, with power off and USB

disconnected, move the JU1 shunt between pins 2-3.
