  • LM15851: initialization sequence

    Resolved
    Part Number: LM15851 Hi! I have some questions regarding LM15851 initialization. 1. Does SPI_RES (POR register) supersede SWRST (CFGA register). I.e. SPI_RES resets the whole chip (including internal state machines, etc.), and SWRST resets register's…

  • LM15851: Driving LM15851 diff SYNC~ input with an LVDS driver

    Resolved
    Part Number: LM15851 Hi! As I've seen in LM15851EVM, SYNC~ input of the LM15851 is directly driven by TSW14J56's FPGA diff output. Is that output is configured as an LVDS output? If so, it doesn't meet common mode voltage requirements for the…
