DESCRIPTION
0 = initial silicon, 1 = first revision, etc.
0x3
0: A signal is not present at the input
1: A signal is present at the input
0: DLL is not locked
1: DLL is locked
0: Inverted Polarity
1: Nominal Polarity
This bit is only valid if the INVERT pin is connected
as an output. If INVERT is overdriven, this value may
not reflect the polarity of the input signal.
0: Signal is monochrome
1: Signal has a colorburst
0: Signal (if present) is within normal range
1: Signal appears to be overloaded
0: EQ is not settled, though DLL may be locked.
1: EQ has stabilized and equalization achieved.
Manual Length Control; 0x0 through 0x3F,
64 feet per bit.
0x0: 0 feet.
0x3F: 5280 feet
This register sets the EQ setting when MegaQ™ is in
manual length mode (reg 0x05[1:0] = 11).
Note that the length in this register is correct for
Cat 5 cable only.
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.
