Part Number: AFE58JD28
Other Parts Discussed in Thread: TPS62916,

Tool/software:

it there possible to provider 1.2V,1.8V,3.3V without LDO for AFE and FPGA? such as TPS62916, or LMT8060.

and how many power need to provider? (AFE58JD28 x 4, 14bit, 50Mbps, JESD, DEMOD)

in the datasheet with 12bit, 80Mbps, use A3.3V = 330mA, A1.8V=170mA, D1.2V=210demod+260jesd=470mA, D1.8V=40mA

    Hi, I can speak on the TPS62916 - Yes the TPS62916 is designed to replace a LDO with low noise and low ripple. 1.2V, 1.8V, 3.3V are all possible.

    For any questions about AFE58JD28 or LMT8060, I will defer to my colleagues.

    Best regards,
