EVALUATION BOARD DESCRIPTION
The EVA L-ADM1260CSZ evaluation board is designed for
evaluating the ADM1260 Super Sequencer® IC. The board is
easy to use, easy to probe, allows flexible wiring, and is capable
of supporting large mutltidevice systems by cascading multiple
boards.
SUPPORTED DEVICES
The evaluation board is designed to support the ADM1260
when the silicon is placed in the SOCKET-ADM106XLFZ
daughter card.
POWER SUPPLIES
The evaluation board can accept 9 V to 14.4 V from a bench
power supply through Connector J5-1 and Connector J5-2. It
also supports a wall mountable switching power supply with the
voltage range 9 V to 14.4 V using Connector J6. Connector J6 is
grounded and has reverse voltage protection circuits to prevent
damage due to incorrect polarity. The current consumption of a
single board depends on the exact configuration of the board
and sequence, but the consumption is typically less than 200 mA.
INPUTS EMULATION
Ten on-board adjustable voltage regulators from Analog Devices
provide input supply emulation for all different setups supported
by the ADM1260.
Each regulator operates independently and the output voltages
can be easily adjusted by hand using an on-board, rotating
potentiometer.
Every regulator can be enabled or disabled by the user or by the
ADM1260 device, depending on the selection switch
configuration. There is an LED to indicate the on/off status for
each regulator.
All regulators have a feedback pin that allows the user to evaluate
the margining function of the ADM1260.
An additional on-board, two-way, push-pull/open-drain switch,
S13, can emulate digital inputs, if required.
OUTPUT SIGNAL
PDOx output signals from the ADM1260 can easily connect to
the regulator enabled control circuits on the board to control the
on-board voltage regulators. The user can easily link the PDOx
output signal to a regulator enable input by using the 10 switches
S12 comprises. Linking the PDOx output signal to a regulator
enable input allows the board to perform simulations for real-
world sequencing applications.
The digital-to-analog converter (DAC) output signals can be
wired to the feedback node of the regulators on the board to
achieve supply margining.
The wiring of the DAC output to the feedback node of the
regulator is made easy with the point to point patch cables
included in the evaluation kit. The user can easily connect the
DAC outputs of the ADM1260 to a regulator feedback node.
EVAL-ADM1260EBZ User Guide UG-932
Rev. 0 | Page 5 of 20
I²C INTERFACE
The evaluation board supports an I²C interface. The user can
connect the I2C end of the dongle from the PC USB port to the
board using the USB-SDP-CABLEZ. The dongle has internal
pull-ups for the SDA and SCL bus.
MULTIPLE BOARD SETUP
Connector SK2, Connector SK3, and the eight-way ribbon cable
allow up to four EVA L-ADM1260CSZ boards to connect to
evaluate complex cascade sequencing setups.
A connection cable carries power and the interchip bus (ICB) to
every board that is connected together. The user must only connect
the power and the USB-SDP-CABLEZ to one board. It is recom-
mended to connect the power supply to the board in the middle
of a multiple board setup to ensure even power dissipation in
the traces/cables.

MARGINING GUIDE
The ADP7102 LDO in the evaluation board provides adjustable
VXx and VPx input voltages to the VXx and VPx pins.
The DAC1, DAC2, and DAC3 outputs, labeled on the board as
X1, X2, and X3, are designed for VXx supply margining to the
board. The DAC4 and DAC5 outputs, labeled on the board as
X4 and X5, are designed for VPx supply margining. DAC6, labeled
on the board as X6, is designed for VH supply margining.
For margining the supplied voltage, the output of the DACs
must connect to the feedback node of the LDOs. The connectors to
the VXx feedback nodes are labeled T1 to T5, the VPx feedback
nodes are labeled T7 to T10, and the VH feedback node is
labeled T6.
The reference voltage of the ADP7102 is 1.22 V, so the midcode
of the DACs must be set as 1.25 V to achieve the highest maximum
and minimum range for margining the rails.

QUICK START GUIDE
HARDWARE SETUP
1. Put Jumpers J1, J2, J3, and J4 into Position H on the board.
This puts the output of the VPx regulators to higher voltage
ranges.
2. All the jumpers comprised in the J5 jumper must be populated
since J5 connects the output of the voltage regulator to the
respective input pins, VPx, VXx, and VH, of the sequencer.
3. Put Switches S1 to S10 into the bottom position. This
enables the voltage regulators connected to the Pin VXx and
Pin VPx input to be controlled by an external signal such as the
PDOx pins of the ADM1260.
4. Set all the switches S12 comprises to the on position which
connects the PDOx pins to the enable pins, EN-VXx, EN-
VPx, and EN-VH, of the LDO in the board of the voltage
regulator as shown in Table 2.

DEMONSTRATION CONFIGURATION
To download the demo configuration files, go to the ADM1260
product page. The file contains two configuration files: one
demonstrates the single device functionality of the ADM1260
and the other demonstrates multiple device functionality of
ADM1260.
DEMO 1: SINGLE BOARD SEQUENCING
In this demonstration, the PDOx signals are turned on one by
one by the sequence configuration to enable the voltage regulators.
The VXx rails are the first to come up followed by the VPx rails.
The ADM1260 is powered by the VH rails in this particular
demo, which is done by setting Switch S14 to PWR. Set the
device address to 0x34; refer to Table 3 for more information.
The sequence engine turns on a rail and checks if that particular
rail has either an undervoltage (UV) or overvoltage (OV) fault.
If there is no fault in the rail for 200 ms, the sequence proceeds
to the next rail until all the rails are up. If either the UV or OV
fault persists in the rails that the sequence engine is trying to
sequence, the sequence engine times out after 400 ms and tries
to sequence all the rails again.
If a fault happens in any of the rails that are already powered up
while the sequence engine is sequencing or is in the power good
state, the sequence engine jumps to the power fail state and tries
to sequence the rails. In the power fail state, the ADM1260 does
a black box write.
The OV thresholds are set to 1.30 V for the VXx pins and 3.5 V
for the VPx pins. UV thresholds are set to 1.00 V for the VXx pins
and 3.1 V for the VPx pins. For the demonstration configuration to
sequence as expected, the voltage for the VXx pins and VPx pins
must be set in within the UV and OV thresholds.
DEMO 2: MULTIPLE BOARD SEQUENCING
(TWO BOARDS)
This demonstration shows sequencing across three boards and
the function of ICB bus. Three boards must connect serially
using the SK2 and SK3 ports. The boards must have an SMBus
address of 0x34 and 0x35. When multiple evaluation boards are
connected together, only one I2C dongle and power source is
required since the serial connecting cable carries the power, the
I2C lines, and the ICB lines across the boards.
The sequence configuration for this demo enables the PDOx
signals one by one to enable the LDOs. The VXx rails on the
ADM1260 are the first to come up followed by the VPx rails.
The sequence configuration is made to enable one rail per device
in every state, showing the robustness of multidevice sequencing.
The sequence enables Pin VX1 on Device 0x34, followed by
Pin VX1 on Device 0x35, Pin VX2 on Device 0x34, and so on.
The sequence engine turns on a rail and checks if that particular
rail has a UV or OV fault. If there is no fault for 200 ms, the
sequence engine proceeds to the next rail until all the rails are
powered up on the three boards. If either the UV or OV fault
persists in the rail that the sequence engine is trying to sequence,
the sequence engine times out after 400 ms and tries to sequence
all the rails again.
If a fault happens in any of the rails that are already powered up
while the sequence engine is sequencing or in the power good
state, all three devices jump to the power fail state and try to
sequence the rails again.
The OV thresholds are set to 1.30 V for the VXx pins and 3.5 V
for the VPx pins. The UV thresholds are set to 1.00 V for the
VXx pins and 3.1 V for the VPx pins. For the demonstration con-
figuration to sequence as expected, the voltage for the VXx pins
and VPx pins must be set in between the UV and OV thresholds.
