ADC3660EVM Evaluation Module
1 Introduction
The ADC3660EVM is an evaluation board used to evaluate the ADC3660 analog-to-digital converter (ADC) from Texas Instruments. The ADC3660EVM is a dual-channel, 14-bit ADC that can operate up to 65 Mega-samples per second (MSPS). The ADC3660 uses a serial CMOS (SCMOS) interface to output the data. The serialized CMOS interface supports output rates to 250 Mbps which translates to ~ 15 MSPS (2-wire) to ~ 3.75 MSPS (0.5-wire) output rates after complex decimation. Hence the ADC3660 can be operated in 'oversampling + decimating' mode using the internal decimation filter in order to improve the dynamic range and relax external anti-aliasing filter.
The ADC3660EVM is equipped with the following features:
- Transformer and FDA coupled analog inputs
- Transformer coupled or single-ended clock inputs
- INA226 current shunt monitors for evaluating power consumption
- FMC connector
- CDCE6214 clocking solution for on-board clocking
2 Equipment
This hardware setup procedure is written to use the onboard CDC clocking option. Interrnal clock operation.
2.1 Evaluation Board Feature Identification Summary
Figure 2-1 ADC3660EVM Feature Identification. Ensure that jumper J8 is shunted in the 2-3 position. This allows 5 V to be supplied to the ADC3660EVM through the mini-USB connector.
If an external 5-V supply is desired, J8 must be shunted in the 1-2 position, and the external 5 V can be connected to the test point labeled "+5 EXT".

The following equipment is included in the EVM evaluation kit:
- ADC3660 Evaluation board (EVM)
- CMOS FPGA Interposer Card
- Power supply clips for Interposer Card
- Mini-USB cable
The following equipment is not included in the EVM evaluation kit, but is required for evaluation of this EVM:
- TSW1400EVM data capture board and related items
- HSDC Pro software
- PC running Microsoft® Windows® 7, or 10
- Two low-noise signal generators for the sampling clock (optional: for external clock option) and analog input.
TI recommends the following generators:
- Rohde & Schwarz SMA100A
- Rohde & Schwarz SMA100B
Bandpass filter for the analog input signal. The following recommended bandpass filter will have:
- Bandpass filter, greater than or equal to 60-dB harmonic attenuation, less than or equal to 5% bandwidth, greater than 18-dBm power, less than 5-dB insertion loss
- Signal-path cables, SMA
