LTM8060

Demonstration circuit 2820A features the LTM8060 μModule^® regulator, a quad output high-performance step-down Silent Switcher^® μModule regulator in a thermally enhanced 11.9mm × 16mm × 3.32mm BGA package. DC2820A has a wide operating input voltage range of 5.4V to 40V. The output rails are configured for 5V, 3.3V, 1.5V, 1.2V and are resistor programmable from 0.8V to 8V. Each output can provide up to 3A and phases can also be paralleled together to satisfy higher rail current requirements. The LTM8060 is a complete multioutput DC/DC point of load regulator in a compact form factor, requiring only a few input and output capacitors and resistors to set the output voltages and operating frequency. Output voltage tracking is made available by the TRSS pins for supply rail sequencing. External clock synchronization is available through the SYNC pins, CLKOUT pins provide for optional synchronization of additional phases. For reduced noise, Spread Spectrum operation is available via SYNC pin programming. The LTM8060 data sheet must be read in conjunction with the DC2820A demo manual for working on or modifying demo circuit 2820A.

• Transmit and receive frequency X band: 8GHz to 12GHz
• Direct sampling in L, S, and C bands with capacitor rotation
• Multichannel, wideband system development platform for the AD9084 
• Mates with Xilinx VCU118 evaluation board (must be purchased separately)
• 16× RF receive channels (32× digital receive channels)
  • Total 16× 4GSPS to 20GSPS ADC channels
  • 48× digital downconverters (DDCs) and complex NCOs
  • 16× programmable finite impulse response filters (pFIRs)
  • 16× complex finite impulse response filters (CFIRs)
• Complete power management solution for all domains

This user guide serves as the main source of information for system engineers and software developers using the ADXBAND16EBZ. This platform contains four AD9084 software-defined, direct sampling mixed-signal front end (MxFE), including an RF front end, clocking, and power circuitry. Common target applications are phased array radars, electronic warfare, and ground-based SATCOM. The receive and transmit RF front ends have bypass configurations that allow customized frequency ranges of less than 8GHz up to 18GHz.

The ADXBAND16EBZ highlights a complete system solution. This platform is intended as a testbed for demonstrating multichip synchronization as well as the implementation of system-level calibrations and signal processing algorithms. The system is designed to mate with a Xilinx VCU118 evaluation board, which features the Virtex UltraScale+ XCVU9P field-programmable gate array (FPGA), with provided reference software, hardware design language (HDL) code, and MATLAB system-level interfacing.

A 16 transmit and 16 receive calibration board (ADXBAND16EBZCAL) can be used to develop system-level calibration algorithms to demonstrate power-up phase determinism. The calibration board demonstrates combined-channel dynamic range, spurious, and phase noise improvements that can also be controlled via a MATLAB add-on when connected to the peripheral module (PMOD) interface of the VCU118.
