4.6.5

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

I/O AC Parameters

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

•

General Purpose I/O (GPIO)

•

Double Data Rate I/O (DDR) for LPDDR2 and DDR3/DDR3L modes

•LVDS I/O

The GPIO and DDR I/O load circuit and output transition time waveforms are shown in Figure 4 and

Figure 5.

1 OVDD – I/O power supply (1.425 V–1.575 V for DDR3 and 1.283 V–1.45 V for DDR3L).

2 Vref – DDR3/DDR3L external reference voltage.

3 The single-ended signals need to be within the respective limits (Vih(dc) max, Vil(dc) min) for single-ended signals as well as

the limitations for overshoot and undershoot (see Table 29).
