TIDA-010132
Multichannel RF transceiver reference design for radar applications
TIDA-010132
Overview
This reference design, an 8-channel analog front end (AFE), uses two AFE7444 4-channel RF transceivers and LMK04828-LMX2594-based clocking subsystem which can enable designs to scale to 16 channels or more. Each AFE channel consists of a 14-bit, 9GSPS DAC and a 3GSPS ADC that is synchronized to less than 10ps skew with > 75-dB dynamic range at 2.6GHz.
Features
- High density, scalable 8-channel RF sampling analog frontend with single FMC interface
- System clock skew less than 5 psec across devices
- Clock phase adjustment with 0.5 psec step resolution
- Low noise clock generation for 14-bit analog frontend performance
- Digital function (NCO, DDC and so forth) synchronization across multiple transceivers
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
