Legend:
TAGC = AGC stabilization time
TE = Time element of pulse
TGAP = AGC stabilization gap
TOEH = Minimum output enable filter high time
TOEL = Minimum output enable filter low time
TOET = Maximum output enable filter period
TPAGC = High time after TAGC
TSTAB = TAGC + TPAGC
t ≥ TOEL
t ≥ TE
Filter is passed and
LFDATA is enabled
