Purpose
1-2
1.1 Purpose
The ADS5410 EVM provides a platform for evaluating the ADS5410
analog-to-digital converter (ADC) under various signal, reference, and supply
conditions. Use this document in combination with the EVM schematic
diagram supplied.
1.2 EVM Basic Functions
Analog input to the ADC is provided via two external SMA connectors. The
single-ended input the user provides is converted into a differential signal at
the input of the device. One input uses a differential amplifier, while the other
input is transformer coupled.
TheEVMprovidesanexternalSMAconnectionforinputoftheADCclock.The
usercansendthisclocktotheoutputconnectorwiththedigitaldataorprovide
asecondclocksourcetobesentinplaceoftheADCclock.Thisallowstheuser
to provide the required setup and hold times of the output data with respect to
theoutputclock.Seethe Clock Inputssectionfortheproperconfigurationand
operation.
DigitaloutputfromtheEVMisviaa40-pinconnector.Thedigital linesfromthe
ADC are buffered before going to this connector. More information on this
connector can be found in the ADC output section.
PowerconnectionstotheEVMareviabananajacksockets.Separatesockets
are provided for the analog and digital supply.
1.3 Power Requirements
The EVM can be powered directly with only a 1.8-V and 3.3-V supply if using
themodulewithatransformer coupledinputandaninternalreferencesource.
A voltage of ±5 V is required if using the differential amplifier input. Provision
hasalsobeenmadetoallowtheEVMtobepoweredwithindependentanalog,
digital, and I/O supplies to provide higher performance.
Voltage Limits
Exceeding the maximum input voltages can damage EVM
components. Undervoltage may cause improper operation of
some or all of the EVM components.

Overview
1.4 ADS5410 EVM Operational Procedure
The ADS5410 EVM provides a flexible means of evaluating the ADS5410 in
anumberofmodes of operation. A basic setupprocedurethatcanbeusedas
a board confidence check is as follows:
1) Verify all jumper settings against the schematic jumper list in Table 1–1
and Table 1–2:

W3 Transformer and diff amp
common mode select ADC output common mode voltage N/A 1–2
W6 Power-down select Power-down mode Operate mode 2–3
W1 Reference select N/A Internal reference 2–3
2) Connect supplies to the EVM as follows:
J1.8-V digital supply to J9 and return to J10
J3.3-V driver supply to J13 and return to J14
J3.3-V analog supply to J6 and return to J5
3) Switch power supplies on.
4) Use a function generator with 50-Ωoutput to input a 80-MHz differential
sinewave,0-Voffset,1V(p-p)to6V(p-p).ToprovidetheADCclock,connect
the positve output into J3 and the negative output into J16.
Note:
The frequency of the clock must be within the specification for the device
speed grade.

5) Use a function generator with 50-Ωoutput to input a 1.5-V offset, 3-V(p-p)
amplitude square wave signal into J4 to be used as the buffered output
clock.
Note:
This signal must be the same frequency and synchronized with the ADC
clock.
6) Useafrequencygeneratorwith 50-Ωoutputtoinputa17-MHz,0-Voffset,
1.5-V(p-p) amplitudesinewavesignalintoJ2.Thisprovidesatransformer
coupled differential signal to the ADC.
7) The digital pattern on the output connector J15 now represents a sine
wave and can be monitored using a logic analyzer.
