6.3.7 High-Speed Data Output
The high-speed data output driver consists of a voltage mode logic (VML) differential pair optimized for a 50-? impedance environment. The magnitude of the differential-pair signal swing is compatible with pseudo emitter coupled logic (PECL) levels when AC coupled. The line can be directly coupled or AC coupled. See Figure 6-7 and Figure 6-8 for termination details. The outputs also provide preemphasis to compensate for AC loss when driving a cable or PCB backplane trace over a long distance (see Figure 6-3). The level of preemphasis is controlled by PRE (see Table 6-2).

| PRE | PREEMPHASIS LEVEL (%) VOD(P), VOD(D)(1) |
|---|---|
| 0 | 5% |
| 1 | 20% |
(1) VOD(p): Voltage swing when there is a transition in the data stream.
VOD(d): Voltage swing when there is no transition in the data stream.
VOD(d): Voltage swing when there is no transition in the data stream.
