3 Description
The is a high performance, wide bandwidth
multi-channel transceiver, integrating eight RF
sampling DACs and 10 RF sampling ADCs. Pin
and programming compatible lower channel count
versions (AFE8004 with 4TX and 4RX channels,
AFE8010 with 10RX channels) are available to allow
scalable system designs.
Each receiver (RX) chain includes a 25 dB range
DSA (Digital Step Attenuator) followed by a 4 GSPS
ADC (analog-to-digital converter). The 10 ADCs are
connected to 8 receiver paths (1RX though 8RX)
and 2 feedback paths (1FB and 2FB). The ADCs
are identical between RX and FB but the digital
down converter paths are different (the FB paths
are capable of wider bandwidth and can be used as
receivers). Each receiver channel has analog peak
power detectors and digital peak and power detectors
to assist an external or internal autonomous automatic
gain controller, and RF overload detectors for device
reliability protection. The single or dual digital down
converters (DDC) provide up to 800 MHz of signal BW
for 8 channels or 400 MHz for 8 channels in addition
to 800 MHz for 2 channels.
Each transmitter (TX) chain includes a single or dual
digital up converter (DUC). Supporting up to 800 MHz
signal bandwidth for eight channels or 1200 MHz for 4
channels. The output of the DUCs drives a 12-GSPS
DAC (digital-to-analog converter) with a mixed mode
output option to enhance 2nd Nyquist operation. The
DAC output includes a variable gain amplifier (TX
DSA) with 40 dB range and 1 dB analog and 0.125
dB digital steps.
