Ti95 HSIO2

Each HSIO2 block uses a pair of I/O pins as one of the following:

  • Single-ended HSIO2—Two single-ended I/O pins (LVCMOS, SSTL, HSTL)
  • Differential HSIO2—One pair of differential I/O pins:
    • Differential SSTL and HSTL
    • LVDS—Receiver (RX), transmitter (TX), or bidirectional (RX/TX)
    • MIPI lane I/O—Receiver (RX) or transmitter (TX)

Important: When you are using an HSIO2 pin as a GPIO, make sure to leave at least one pair of unassigned HSIO2 pins between any GPIO and LVDS or MIPI lane pins. This rule applies for pins on each side of the device (top, bottom, left, right). This separation reduces noise. The Efinity software issues a warning if you do not leave this separation.
