The AFE7444 is a quad-channel, wideband, RF-sampling analog front end (AFE) based on 14-bit, 9-GSPS DACs and 14-bit, 3-GSPS ADCs. With operation at an RF of up to 6 GHz, this device enables direct RF sampling into the C-band frequency range without the need for additional frequency conversions stages. This improvement in density and flexibility enables high-channel-count, multimission systems.

The DAC signal paths support interpolation and digital up conversion options that deliver up to 800 MHz of signal bandwidth. The differential output path includes a digital step attenuator (DSA), which enables tuning of output power.

Each ADC input path includes a dual DSA and RF and Digital power detectors. Flexible decimation options provide optimization of data bandwidth.

An 8-lane (8 TX + 8 RX) subclass-1 compliant JESD204B interface operates at up to 15 Gbps. A bypassable on-chip PLL simplifies clock operation with an optional clock output.
