Name aLosHyst[3:0] Reserved aLosThresh[9:8]
Type R/W R R/W
Bit Name Function
7:4 aLosHyst[3:0] Analog Loss of Signal Hysteresis.
Analog
LOS deassert value = (aLosHyst + 16)/16 * aLosThresh in mVppd.
3:2 Reserved Read returns zero.
1:0 aLosThresh[9:8] Analog Loss of Signal Threshold.
Upper two bits of the analog threshold value in mVppd.
Notes:
1. Maximum analog LOS threshold is 400 mVppd.
2. Combined with Register 12,
00 0000 1010 = 10 mVppd minimum.
01 1001 0000 = 400 mVppd maximum.
Register 15. peakDet

Name peakDet[7:0]
Type R
Bit Name Function
7:0 peakDet[7:0] Peak Detector Signal Amplitude.
Least significant byte of the receiver peak detector signal amplitude in mV. This register
should be read before register 16.
