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

4.6.6

MLB 6-Pin I/O DC Parameters

The MLB interface complies with Analog Interface of 6-pin differential Media Local Bus specification

version 4.1. See 6-pin differential MLB specification v4.1, “MediaLB 6-pin interface Electrical

Characteristics” for details.

NOTE

The MLB 6-pin interface does not support speed mode 8192fs.

Table 27 shows the Media Local Bus (MLB) I/O DC parameters.

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 31).
