Overview
The ADC32RF45 EVM is an evaluation module (EVM) designed to evaluate the ADC32RF45 family of
high-speed, JESD204B interface ADCs. The EVM includes an onboard clocking solution (LMK04828),
transformer-coupled analog inputs, full power solution, and easy-to-use software GUI and USB interface.
The following features apply to this EVM:
•
Transformer-coupled signal input network allowing a single-ended signal source from 30 MHz to 3000
MHz.
•
LMK04828 system clock generator that generates field-programmable gate array (FPGA) reference
clocks for the high-speed serial interface and may optionally be used to generate the ADC sampling
clock.
•
Transformer-coupled clock input network to test the ADC performance with a very low-noise clock
source
•
LMX2582 (or LMX2592) clock synthesizer to generate a very low-noise clock source for clocking the
ADC32Rf45 ADC.
•
High-speed serial data output over a standard FPGA Mezzanine Card (FMC) interface connector.
The ADS54J45 EVM is designed to work seamlessly with TI's TSW14J56 EVM JESD204B data
capture/pattern generator card, through the High Speed Data Converter Pro (HSDC Pro) software tool for
high-speed data converter evaluation. The ADC32RF45 EVM is also designed to work with many of the
development kits from leading FPGA vendors that contain an FMC connector.
1.1
Required Hardware
The following equipment is included in the EVM evaluation kit:
•
ADC32RF45 evaluation board (EVM)
•
Power supply cable
•
Mini-USB cable
The following list of equipment are items that are not included in the EVM evaluation kit but are items
required for evaluation of this product in order to achieve the best performance:
•
TSW14J56EVM data capture board, two 5-V power supplies, and mini-USB cable
•
Computer running Microsoft
•
One low-noise signal generator. Recommendations:
– RF generator, > +17 dBm, < –40 dBc harmonics, < 500 fs jitter 20 kHz–20 MHz, 10-MHz to 3-GHz
frequency range
Examples: HP HP8644B, Rohde & Schwarz SMA100A
•
Bandpass filter for desired analog input. Recommendations:
– Bandpass filter, ≥ 60-dB harmonic attenuation, ≤ 5% bandwidth, > +18-dBm power, < 5-dB insertion
loss
Examples: Trilithic 5VH-series Tunable BPF, K&L BT-series Tunable BPF, TTE KC6 or KC7-series
Fixed BPF
•
Signal path cables, SMA or BNC with BNC-to-SMA adapters
