Connect SDIn to shield of cable via termination network. External 15Ω resistors required. 11, 10 SDOp/SDOn CML Output Serial output positive/negative differential serial output. Output has a swing of 2x600 mV and has 2x50Ω on-chip termination resistors. 5 LFI Input Uplink input signal. LVTTL signal with 1.2V input swing. External series resistor is required for 2.5V (3.9 kΩ) or 3.3V (6.2 kΩ) input swing. 6 AmpR Input Connected to VCC by a resistor that selects output swing of the uplink signal. Typical value is Ramp = 1.2 kΩ for rise/fall times of 11 ns. 7 RiseR Input Connected to VCC by a resistor that selects rise time of the uplink signal. Typical value is Rrise = 10 kΩ for rise/fall times of 11 ns. 8, 14, 15 NC — Do not connect. Leave these pins floating. Used for internal testing.
