FM_NODE[7]_AV 14
HS_OUT
Serial Data Outputs: High-speed outputs to a hard disk drive or to a cable input.
HS_IN
Serial Data Inputs: High-speed inputs from a hard disk drive or from a cable output.
I-LVTTL
Bypass Inputs: For “disk bypassed” mode, connect BYPASS[n]- to GND through a1k resistor.
For “disk in loop” mode, float HIGH.
O-LVTTL
Amplitude Valid: Indicates acceptable signal amplitude on the FM_NODE[7]± inputs.
If (FM_NODE[7]+ - FM_NODE[7]-) >= 400 mV peak-to-peak, FM_NODE[7]_AV = 1
If 400 mV > (FM_NODE[7]+ - FM_NODE[7]-) > 100 mV, FM_NODE[7]_AV = unpredictable
If 100 mV >= (FM_NODE[7]+ - FM_NODE[7]-), FM_NODE[7]_AV = 0
