Description for the AFE7444

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 enablesdirect RF sampling into the C-band frequency range without the need for additional frequencyconversions 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 deliverup to 800 MHz of signal bandwidth. Thedifferential output path includes a digital step attenuator (DSA), which enables tuning of outputpower.

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 15Gbps. A bypassable on-chip PLL simplifies clock operation with an optional clock output.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
