2 Getting Started
The EVM is shipped in a pre-configured state that allows a customer to evaluate the basic driver and
comparator output performance as well as the PMU Force Voltage (FV) / Force Current (FI) modes.
Figure 2 provides an illustration of the recommended interconnections to the Venus EVM. However due
to equipment availability, the EVM can easily and quickly be configured for different options.
2.1 Loadboard and Motherboard Revisions
This document only supports the Loadboard Rev F+ and the Motherboard Rev D+.
For earlier Loadboard & Motherboard revisions, please contact Elevate Semiconductor for the appropriate
documentation.
2.2 Venus and ISL Product Families
The Loadboard supports all of the various Venus and ISL Products: Venus, Venus3, Venus4, ISL55161,
ISL55162, ISL55163, and ISL55164. The Venus4, ISL55161and ISL55163 devices redefined a handful
of pins. To support the different products, the loadboard installs/removes several components to support
the different features. Refer to Section 3 for details. Also refer to the schematic and datasheets.
2.3 Default Configuration Setup Options
The EVM has several default options for providing a DATA stream and/or configuring for PMU mode.

2.3.1 Real Time Data
Figure 2 illustrates the recommended EVM configuration. This option sources the DATA# from a Pulse
Generator. The ENABLE# is set to CPU Control and high (always enabled). The SV# is set to CPU
Control and low (always disabled/open). The DATA# input term is set to 100 Ohm. This option works
best if the customer has a differential pulse generator with at least a 200mV swing.
The DATA#_MON and Comparator Outputs (CA#) have a 953 ohm pick-off. The scope should be set to
50 ohm termination with an attenuation factor of 20.
Note: Channel #1 could be connected in a similar fashion, not shown in diagram. Both channels are
configured the same.
If the customer only has a single ended pulse generator, then the DATAN# can be tied to 1.0V (Vterm);
the Vterm must be able to handle any current flow required for proper termination. Set the pulse
generator to a 0.0V to 3.0V swing. Select the Single Ended RT Data from the EVM Setup configuration
menu. The DATA# input term is set to NONE.

2.3.2 Ring Oscillator Mode (No Pulse Generator)
Figure 3 illustrates a possible configuration for customers without any pulse generator. This option uses
the Ring Oscillator feature to generate a ~20 MHz pulse with a ~15 nS pulse width. All deskews are
enabled and set to zero delay. Both channels are configured the same. This option is not available on
the ISL55163.
The Comparator Outputs (CA#) have a 953 ohm pick-off. The scope should be set to 50 ohm termination
with an attenuation factor of 20.

2.3.3 LVDS Outputs Real Time Data
Figure 2 illustrates the EVM configuration for generating LVDS Outputs. A Low Voltage Differential
Signal (LVDS) is defined as Vcm=1.25V and Vswing=350mV into a 100 Ohm termination.
The input data stream is feed into DATA#0. Channel #1 also sources its data from DATA #0 using
Venus’s internal cross point switch. The Channel #1 signal is then inverted using the DATA-XOR feature.
The driver DVH/DVL levels are programmed to 1.6V and 0.9V respectively. The ENABLE# is set to CPU
Control and high (always enabled). The SV# is set to CPU Control and low (always disabled/open). The
DATA# input term is set to 100 Ohm.
The user is responsible for programming the deskew values such that the 2 waveforms align. Failure to
program the deskew values could result in poor output waveforms. The Driver Deskew Delay and Falling
Edge Adjust (FEA) are enabled and set to 0.
There are 2 options to connecting the outputs to a scope.
Scope setup option 1: (true LVDS levels)
Connect a 100 Ohm resistor between DOUT0 and DOUT1. Use a 953 Ohm pick off connected to the
Scope’s 50 Ohm input. This will result in a 20X attenuation, the scope should be configured accordingly.
The 953 Ohm pick off is used to minimize reflections, this will also cause a 5% drop in the output
voltages.
Scope setup option 2: (pseudo LVDS levels)
Connect the DOUT0 and DOUT1 to the Scope’s 50 Ohm input, the probe attenuation should be set to 1.
The scope’s two 50 Ohm resistors are used to create a 100 Ohm termination between Channel #0 and
Channel #1. The main difference is that the Vcm will be 0V (GND) instead of 1.25V. The user needs to
program the driver DVH/DVL to +0.350V and -0.350V respectively.

2.3.4 Channel #0 in Real Time DATA and Channel #1 in Compare Only
Figure 5 illustrates a possible configuration for customers to evaluate the Driver and Compare only
modes. To evaluate the Driver, connect a differential pulse generator to the DATA_0 SMAs. To
evaluate the Comparator Only mode, connect a single-ended pulse generator into the Venus DOUT_1
SMA.
Channel#1 will be set to VTT Mode (50 Ohm termination) with the VTT Level set to 1.5V. The Channel#1
comparator thresholds are also set to 1.5V. The pulse generator should be set to swing around 1.5V. If
other pulse generator levels are required, change the Venus VTT level and comparator thresholds as
required.
Note: to put Channel#1 into HiZ mode instead of VTT mode, change the DR-Mode setting found in
Product(ISL55161, ISL55162, etc…)->Channel 1->Driver Path Config
The 2 channels will run asynchronously since the 2 pulse generators are asynchronous.
The DATA#_MON and Comparator Outputs (CA#) have a 953 ohm pick-off. The scope should be set to
50 ohm termination with an attenuation factor of 20.

2.3.5 PMU Force Voltage or Force Current Modes
Figure 6 illustrates the recommended configuration for PMU FV/FI evaluation. The external measurement
unit (MU) should be configured in the opposite mode as Venus. After the configuration is completed, use
the PMU FV/FI Levels dialog box the change the Venus output levels.

2.3.6 PMU Chan#0 in FV and Chan#1 in FI
Figure 6 illustrates the configuration for PMU Chan #0 FV and Chan #1 FI evaluation. The other channel
is used to provide a proper load (current load or voltage load depending on which channel is being
evaluated). This option is useful when the customer doesn’t have an external measurement unit.
Instead, the customer can use two DMMs to evaluate the Venus PMU.

2.3.7 Real Time PMU SV & Driver DVL using EN or SV Inputs
Figure 8 illustrates the configuration that uses the EN input to toggle the DOUT output between PMU FV
(SV) and Driver DVL. In this application, the PMU FV is used to create the Super Voltage (SV) output.
The PMU FV can output up to the VCC_SV (13V) supply minus headroom while the Driver uses the VCC
(8V) supply.
The Driver is set to Real-Time Enable with CPU-DATA=0 (DVL); DVL is set to 0V. The PMU is set to
Real-Time using the inverted Enable signal. The PMU is set to 12V in VR2, IR7 (32mA), and Tight
feedback. The 32mA is chosen since that has the fastest response time. The PMU needs to be in Tight
loopback to prevent the PMU from going into open loop when the SV switch is open.

 Channel #0: Short E5 & E6 (on Motherboard) between Pin 2-3 (towards front of board)
 Channel #0: Connect differential pair to EN_0 & ENN_0 SMA connectors (on Motherboard)
Transitioning from DVL to FV (SV) requires about 100nS. Therefore the pulse generator should be set
accordingly.
Real Time SV Option
To optionally use the Real Time SV input to toggle between PMU FV (SV) and HiZ:
 Start with the Real Time SV / DVL using Enable setup
 Set Sel-SV-EN = SV in the Product(ISL55161, ISL55162, etc…)->Channel 0->Driver Path
Config dialog box
 Channel #0: Short E7 (on Motherboard) between Pin 2-3 (towards front of board)
 Channel #0: Connect pulse generator to SV_0 SMA connector (on Motherboard)
 The Driver must be disabled. Either set the EN inputs to a static low or set Sel-RT-EN = CPU EN
and set CPU-EN Value = Low.

Note: DOUT should be connected to a Rload so DOUT gets pulled to GND when DOUT is in HiZ.
