Table 19. LVDS-ANSI/LVDS-IEEE Options

BIT 6

OUTPUT MODE

OUTPUT DRIVER CURRENT

LVDS-ANSI (default)

Automatically selected to give proper swing.

LVDS-IEEE reduced range link

Automatically selected to give proper swing.

Bits[5:3]—Open

Bit 2—Output Invert

Setting this bit inverts the output bit stream.

Bit 1—Open

Bit 0—Output Format

By default, this bit is set to send the data output in two’s complement format. Clearing this bit to 0 changes the

output mode to offset binary.

Output Adjust (Register 0x15)

The power-on default value of this register is 0x00.

Bits[7:6]—Open

Bits[5:4]—Output Driver Termination

These bits allow the user to select the internal termination resistor.

Bits[3:1]—Open

Bit 0—Output Driver

Bit 0 of the output adjust register controls the drive strength on the LVDS driver of the FCO and DCO outputs only.

The default value setsthe drive to 1×, or the drive can increase to 2× by setting the appropriate channel bit in Register

0x05 and then setting Bit 0, Register 0x15. These features cannot be used with the output driver termination select.

The termination selection takes precedence over the 2× driver strength on FCO and DCO when both the output driver

termination and output driver are selected.

Output Phase (Register 0x16)

The power-on default value of this register is 0x03.

Bit 7—Open

Bits[6:4]—Input Clock Phase Adjust

When the clock divider (Register 0x0B) is used, the applied clock is at a higher frequency than the internal sampling

clock. Bits[6:4] of Register 0x16 determine at which phase the external clock sampling occurs. The input clock phase

adjust is only applicable when the clock divider is used. Selecting a value for Bits[6:4] greater than Register 0x0B,

Bits[2:0] is prohibited. See Table 20.

Bits[3:0]—Output Clock Phase Adjust

For more details, see Table 21.
