DESCRIPTION

0: Use value of FREEZE pin.

1: Use value in âFreeze Valueâ bit

If Freeze Select = 1, then:

0: Equalization is not frozen

1: Equalization is frozen at current setting.

If Freeze Select = 0, then this bit is ignored.

0: Use value of EQ_DISABLE pin.

1: Use value in âEq-Disable Valueâ bit

If Eq-Disable Select = 1, then:

0: Equalizer is enabled

1: Equalizer is disabled (allows data to be sent upstream over

cable pair connected to inputs)

If Eq-Disable Select = 0, then this bit is ignored.

0: Use value of COLOR pin

1: Use value in âColor Valueâ bit

If Color Select = 1, then

0: Monochrome Mode

1: Color Mode

If Color Select = 0, then this bit is ignored.

0: Use value of INVERT pin.

1: Use value in âInvert Valueâ bit

If Invert Select = 1, then

0: Incoming signal is not inverted

1: Incoming signal is inverted

If Invert Select = 0, then this bit is ignored.

00 = Continuous Monitoring

01 = Lock Until Signal Loss*

10 = Lock Until Reset

11 = Manual Length**

*Signal must be missing for at least 1ms in order to trigger a

re-equalization.

**In Manual Length mode, the polarity corrector is disabled

and the polarity must be set using the INVERT bit or pin.

Note: The FREEZE pin must be tied to ground/a logic low for

this function to work correctly.

00: No Noise Filtering

01: Min Noise Filtering

10 or 11: Max Noise Filtering

0: Cat 5/Cat 6 Mode

1: Steel Core Coax Mode

This bit is ignored in all modes except Manual Length (reg

0x05[1:0] = 11).

Set to 1 if using copper-coated steel-core coaxial cable and

you are in Manual Length.
