Purpose
1-2
1.1
Purpose
The THS1040/41EVM evaluation module (EVM) provides a platform for
evaluation of the THS1040 and THS1041 10-bit analog-to-digital converters
(ADC) under various signal, reference, and supply conditions. Unless stated
explicitly, the functionality described in this user
’
s guide applies to both
THS1040 and THS1041 devices.
1.2
EVM Basic Functions
Analog input to the THS1040/41 is provided by external SMA connectors. The
input can be configured onboard to be ac, dc, or transformer-coupled to the
input of the device.
An external SMA connector is provided on the THS1041 for the clamp input.
This allows external digital control of the ADC
’
s clamping function. The ADC
can be clamped either to an external reference voltage or from the on-chip
DAC.
The EVM provides an external SMA connection for ADC clock input. The user
can send this clock to the output connector with the digital data or provide a
second clock source to be sent in place of the ADC clock. This allows the user
to provide the required setup and hold times of the output data with respect to
the output clock. Refer to the clock section for proper configuration and
operation.
In addition to the internal reference from the THS1040/41 device, options are
provided on the EVM to allow adjustment of the ADC reference via an onboard
reference circuit.
Output from the EVM is via a 40-pin header connector. The digital lines from
the THS1040/41 are buffered using the SN74LVTH162244 before going to the
header.
Power connections to the EVM are via 4-mm banana sockets. Separate
connectors are provided for the analog and digital supply to the device.
The THS1041 has a number of programmable registers that can be pro-
grammed using DIL switches on the EVM.
1.3
Power Requirements
The EVM has 2 main dc-power supply connections: 3.3 V for the analog and
3.3-V digital supplies to the ADC. Each of these supplies is independent, but
it should be noted that the input thresholds of the ADC varies dependent on
the digital and analog supply voltages, as per the data sheet specification. A
5-V connector is also provided to allow the user to reprogram the CPLD
(THS1041 EVM only).
Voltage Limits
Exceeding the 3.3-V maximum can damage EVM components.
Undervoltage may cause improper operation of some or all of the
EVM components.
