DESCRIPTION
0x00: Maximum DC Gain (+3dB)
0x20: Mid-Scale 0dB
0x3F: Minimum DC Gain (-3dB)
This register sets the DC Gain when the device is in manual
length mode (reg 0x05[1:0] = 11).
0: Use value of FREEZE pin.
1: Use value in “Freeze Value” 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 “Eq-Disable Value” 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 “Color Value” 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 “Invert Value” 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
Note: Noise Filtering is only available on the ISL59605
0: CAT5/6 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.
