Select C
FILTER
For SFP/SFF, FDDI, 155Mbps ATM LAN, Fast Ethernet,
and ESCON receivers, Maxim recommends C
FILTER
=
0.01μF. This capacitor value ensures chatter-free
LOS/SD and provides a typical assert/deassert time of
10μs. For other applications, the value of C
FILTER
can
be calculated using the following equation:
C
FILTER
=
τ
/ 825
where
τ
is the desired time constant of the power detector.
Select C
AZ
and C
IN
External-coupling capacitors (C
IN
) 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 (C
AZ
) connected
between CZP and CZN. The poles associated with C
IN
and C
AZ
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:
C
IN
= 0.01μF
C
AZ
= 0.027μF
