Am7953X Data Sheet
11. Tested with 0
source impedance. 2 M
is specified for system design purposes only.
12. Group delay can be reduced considerably by using a Z
T
network such as that shown in Note 10 above. The network reduces
the group delay to less than 2
μ
s. The effect of group delay on linecard performance may be compensated for by using
QSLAC
or DSLAC
devices.
Note:
* For the Am79534 and Am79535, a logic Low on E0 disables the DET output into the open-collector state.
