(NOTE)
NINITPH
I Phase tracker initialization(active low); If this input
is set to ‘0’, the Phase Tracker is initialized.
NFREEZEPH
I Phase tracker freeze(active low) ; If this input is set to
‘0’, the Phase Tracker stops phase tracking..
When I²C is enabled, operation is performed either using these pins or via I²C register, but
when disabled, only these pins are used. If you want to control Equalizer fast, use these
external input pins. Otherwise use I²C bus registers.

DESCRIPTION
Data output to transport multiplexer;
VSBDATA[7] : Used as start bit indicator of a byte in
serial output mode.
VSBDATA[0] : Used as serial data output in serial
output mode.
Packet error indication flag(active low); This output
indicates whether the packet has error or not.
0 : with error
1 : without error
Valid data indication flag;
1: valid when register64[1](Vsbdvalid_pol = ‘1’)
0 :valid when register64[1](Vsbdvalid_pol = ‘0’)
Start byte indicator of a packet
Data clock of packet data

DESCRIPTION
I²C bus serial clock input
I²C bus serial data input/output
I²C bus enable(active low); If this input is set to ‘0’,
the chip is controlled by I²C bus.
Otherwise, stand alone mode.
I²C bus device address selection;
0 : I²C device address is set to b"1011001".
1 : I²C device address is set to b"0001110".
