Select CFILTER
For SFP/SFF, FDDI, 155Mbps ATM LAN, Fast Ethernet,
and ESCON receivers, Maxim recommends CFILTER =
0.01F. This capacitor value ensures chatter-free
LOS/SD and provides a typical assert/deassert time of
10s. For other applications, the value of CFILTER can
be calculated using the following equation:
CFILTER =
τ / 825Ω
where
τ is the desired time constant of the power detector.
Select CAZ and CIN
External-coupling capacitors (CIN) are required on the
data inputs for the offset correction loop to function
properly. The offset correction loop bandwidth is deter-
mined by the external capacitor (CAZ) connected
between CZP and CZN. The poles associated with CIN
and CAZ must work together to provide a flat response
at the lower -3dB corner frequency. For SFP/SFF, FDDI,
155Mbps ATM LAN, Fast Ethernet, and ESCON
receivers, Maxim recommends the following:
CIN = 4700pF
CAZ = 1F
