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: 4000 feet (Cat 5 mode)
This register sets the EQ setting when 960MegaQ™ is in
manual length mode (reg 0x05[1:0] = 11).
Note that the length in this register is for Cat 5 cable when
“Cable Type” (reg 0x05[4]) equals 0. When “Cable Type” is set
to 1 (coax mode), then the length is for steel core coax. In coax
mode, the maximum length is 0x0F (~1200 feet) and setting
the register higher than this value does not provide any
increase in equalization.
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).
