All thresholds are measured using a pulse with TR =2ms,THIGH = 2ms and TF = 10ms. The repetition rate must not
icrease the PEAK voltage.
NBT represents the noiseblanker byte bits D2, D0 for the noise blanker trigger threshold.
By design/characterization functionally guaranteed through dedicated test mode structure.
NAT represents the noiseblanker byte bit pair D4, D3 for the noise controlled trigger adjustment.
OVD represents the noiseblanker byte bit pair D7, D6 for the over deviation detector.
FSC represents the fieldstrength byte bit pair D1, D0 for the fieldstrength control.
BLT represents the speaker RR byte bit pair D7, D6 for the blanktime adjustment.
NRD represents the configuration byte bit pair D1, D0 for the noise rectifier discharge adjustment.
PCH represents the stereo decoder byte bit D5 for the noise rectifier charge current adjustment.
