Texas Instruments LMX2594RHAR | Demoboard TIDA-010132

Description

This reference design, an 8-channel analog front end (AFE), is demonstrated using two AFE7444 4-channel RF transceivers and a LMK04828-LMX2594 based clocking subsystem which can enable designs to scale to 16 or more channels. Each AFE channel consists of a 14-bit, 9-GSPS DAC and a 3-GSPS ADC that is synchronized to less than 10ps skew with > 75-dB dynamic range at 2.6 GHz.

Features

• 10-MHz to 15-GHz output frequency
• –110 dBc/Hz phase noise at 100-kHz offset with 15-GHz carrier
• 45-fs rms jitter at 7.5 GHz (100 Hz to 100 MHz)
• Programmable output power
• PLL key specifications– Figure of merit: –236 dBc/Hz– Normalized 1/f noise: –129 dBc/Hz– High phase detector frequency– 400-MHz integer mode– 300-MHz fractional mode– 32-bit fractional-N divider
• Remove integer boundary spurs withprogrammable input multiplier
• Synchronization of output phase across multipledevices
• Support for SYSREF with 9-ps resolutionprogrammable delay
• Frequency ramp and chirp generation ability forFMCW applications
• < 20-μs VCO calibration speed
• 3.3-V single power supply operation

Typical applications

• Test and measurement equipment
• High-speed data converter clocking (supports JESD204B)
• 5G and mm-Wave wireless infrastructure / Radar / MIMO / Phased array antennas and beam forming
