Introduction
The AFE5851 includes an 16-channel Voltage-Controlled-Amplifier (VCA) with digital control and an 8channel 65MSPS analog-to-digital converter (ADC). The 16 analog input signals will be processed by the
analog front-end circuit of AFE5851; the outputs of the analog front-end will then be digitalized by the ADC
within the device. There are only eight ADCs within the AFE5851; therefore the odd and even channels
are multiplexed into one LVDS output pair. The output of the ADC is streamed out in serial format. In order
to process the sample data, the Texas Instruments' TSW1400EVM is recommended. The TSW1400
includes a High-Speed LVDS Deserializer, Demultiplexer, and Analysis System which provide a
comprehensive set of hardware and user interface software to effectively evaluate the performance of
AFE5851.

I/O and Power Connectors
The positions and functions of the AFE5851EVM connectors are discussed in this section.
• Analog Inputs Ch1~Ch16 (J1~J16): Single-end analog signals.
• Low Jitter CLK Source Input (J18): This input accepts clocks with low jitter noise, such as HP8644
output. 20~65MHz 50% duty cycle clock with 1~2Vrms amplitude can be used. When J18 is used,
make sure shunt P4,5,6 are removed.
• CLK output (J17): The output of either the U1 output or the on-board 40MHz oscillator output
depending on jumper P4’s connection.
• External CLK Input (J20): ADC Clock input, such as FPGA outputs. FPGA outputs must be processed
by U1. Otherwise, the ADC of AFE5851 will not achieve satisfactory SNR performance.
• +5V PWR connector(P10): Power supply input
• USB input (P11): USB interface to control the AFE5851.
• LVDS Outputs Ch1~Ch8 (P13): Differential LVDS data outputs.

Hardware Setup
As mentioned before, Xilinx DeSerializer ADSDeSER-50EVM or TSW1400EVM is required. See details in
the corresponding application notes on how to use either of these EVMs. An example bench setup is
shown in Figure 10. Band-pass filters are required for signal source in order to ensure the correct SNR
measurements of the AFE5851.
Figure 10. Typical AFE5851 Bench Setup
The channel order of the AFE5851 outputs is not exactly the same as the order of the ADS527x outputs.
As a result, the channel number on the ADSDeSER-50EVM or AFE5851EVM might be misleading.
Table 1 provides channel to channel sequence matching between the ADSDeSER-50EVM and
AFE5851EVM.

For example, when an analog signal is input at CH1 on the AFE5851EVM, the corresponding 12-bit digital
output will be seen at CH8 on the ADSDeSER-50EVM when the AFE5851 is configured as 8-channel
mode.
Current standard ADSDeSER-50EVM can be used to deserialize the AFE5851 LVDS outputs when the
AFE5851 is configured as 8-channel mode. ADSDeSER-50EVM deserialization code for the 16-channel
mode is available from the AFE5851EVM CD. Programming the ADSDeSER-50EVM with a JTAG cable is
necessary.

Clock Selection
AFE5851 is typically clocked through a transformer-based circuit. Other options are also available if
needed as shown in Figure 11.
Figure 11. Clock selection jumper configurations:
(a) Transformer (default); (b) Single-ended clock; (c) Future CLK input option based on U1.
Both (b) and (c) configurations need some modifications on the PCB.
The clock source of the EVM could be the on-board clock 40MHz, HP8644 low jitter clock source, or
external clock source. The best performance of this EVM is achieved when low-jitter clock source HP8644
is used. The P4, P5, P6 should be removed in order to disable the on-board clock.
When HP8644 or similar clock sources are not available, the on-board 40MHz clock is also a desirable
source. The jumpers P4, 5, 6 should be configured as Figure 11 shows (i.e., default setup for
AFE5851EVM). In this mode, the transform-based differential clock is used.
3.6
Data Analysis
Based on the data file acquired by a logic analyzer, the performance of AFE5851 can be evaluated.
Appendix A provides a solution that allows the user to test the performance of all 16 channels using the
TSW1400 EVM to deserialize the AFE5851 outputs and process the FFT algorithms to produce the
spectral analysis plots via the PC.
When the AFE5851 is configured as an 8-channel device and standard ADSDeSer-50EVM is used, all
samples are needed. However, when the AFE5851 is configured as a 16-channel device and nonstandard ADSDeSer-50EVM code is used, even samples and odd samples are corresponding to CHx and
CHx+1 respectively. Please refer to the AFE5851 data sheet for more information on LVDS timing.
