  • AFE7950: AFE7950 5 second startup delay

    Part Number: AFE7950 The AFE7950 takes multiple seconds to startup with the reference design script we were provided. There's a five second delay in the bringupafe() script we were given as part of a reference design, line 21054: dev_spi_write(0x702d…

  • AFE7950: AFE7950 Not Completing Configuration

    Part Number: AFE7950 Other Parts Discussed in Thread: LMK04828 I am working on this issue with Sam Compton at Tomorrow.io. We are bringing up a custom design that uses the AFE7950 interfaced to a Xilinx Virtex UltraScale+ FPGA. The AFE is programmed…

  • AFE7950: AFE7950 RF Output

    Part Number: AFE7950 Hi TI Team, What are the recommended settings for AFE configuration in lattice script to ensure maximum receive power and maximum transmit power at 9.5GHz channel.

  • AFE7950: AFE7950 ZCU102 Contractor

    Part Number: AFE7950 We are interested in migrating a TI-supplied AFE7950EVM reference design to a custom ZCU102 design. This would involve replacing the Microblaze with the A53 and refining the 80k SPI register writes with only the necessary writes.…

  • AFE7950: AFE7950 Incomplete configuration options in Latte

    Part Number: AFE7950 Hi, I have been looking to bring up the AFE7950 with either the Latte tool or the provided register map for a new design we are working on - however I am having some difficulty with both methods. The version of Latte (tool 2.9, framework…
