Description
Serial data true input.
Serial data complement input.
Negative power supply (ground).
Output driver level control. Connect a resistor to VCC to set output voltage swing.
Positive power supply (+3.3V).
Output slew rate control. Output rise/fall time complies with SMPTE 292M when low and
SMPTE 259M when high.
Serial data complement output.
Serial data true output.
Device Operation
INPUT INTERFACING
The LMH0002 accepts either differential or single-ended
input. The inputs are self-biased, allowing for simple AC or
DC coupling. DC-coupled inputs must be kept within the
specified common-mode range. SDI and SDI are self-biased
at approximately 2.1V with VCC = 3.3V. Figure 1 shows the
differential input stage for SDI and SDI.
