Electrical Characteristics

4.3.1.3

LVDS I/O DC parameters

The LVDS interface complies with TIA/EIA 644-A standard. See TIA/EIA STANDARD 644-A,

“Electrical Characteristics of Low Voltage Differential Signaling (LVDS) Interface Circuits” for details.

Table 23 shows the Low Voltage Differential Signaling (LVDS) I/O DC parameters.

4.3.2

I/O AC parameters

This section includes the AC parameters of the following I/O types:

• General Purpose I/O (GPIO)

Figure 4 shows load circuit for output, and Figure 5 show the output transition time waveform.

1 Overshoot and undershoot conditions (transitions above NVCC_XXXX and below GND) on switching pads must be held below

0.6 V, and the duration of the overshoot/undershoot must not exceed 10% of the system clock cycle. Overshoot/ undershoot

must be controlled through printed circuit board layout, transmission line impedance matching, signal line termination, or other

methods. Non-compliance to this specification may affect device reliability or cause permanent damage to the device.

2 To maintain a valid level, the transition edge of the input must sustain a constant slew rate (monotonic) from the current DC

level through to the target DC level, Vil or Vih. Monotonic input transition time is from 0.1 ns to 1 s.

3 Hysteresis of 250 mV is guaranteed over all operating conditions when hysteresis is enabled.
