IMS: 10GHz bandwidth quad-channel Tx Rx analogue front-end

The 16nm CMOS gadget is claimed to have 4 12bit 20Gsample/s ADCs and 4 16bit 28Gsample/s DACs – and looks like a sooner cousin of the 28nm AD9081 launched a number of years in the past – if anybody at IMS learns extra, please remark under.

An enter vary of dc to 18GHz (Ku band) to goes with the 10GHz instantaneous bandwidth is claimed – there are rising 6G bands from 7GHz to 15GHz.

On-chip DSP gives a real-time FFT sniffer, full-rate programmable FIR filter, 128tap advanced FIR filter, hopping NCOs (numerically-controlled oscillators), digital down-converters, digital up-converters, and a fractional pattern charge converter.

The DSP is dynamically-configurable for switching between narrow-band and wide-band profiles with out taking down the JESD hyperlink, mentioned ADI, including that JESD 204B/C and VSR (very brief attain) interfacing might be supported.

It additionally hinted of a 16 channel gadget with eight 8Gsample/s ADCs and eight 16Gsample/s DACs, 16GHz vary and 3GHz instantaneous bandwidth. “On-chip DSP gives related options and performance to the four-transmit four-receive gadget, with double the variety of digital blocks, all dynamically configurable,” added ADI.
