frequency fiber optic applications. The device interfaces directly to the
trans–impedance amplifier of a typical optical to electrical conversion
portion of a fiber optic link. With data rate capabilities in the 622Mb/s
range, the high gain limiting amplification of the LVSX1125 is ideal for high
speed fiber optic applications like SONET/SDM, ATM, FDDI, Fibre
Channel or Serial Hippi. The device is functionally and pin compatible to
the Philips SA5225 with a significantly higher bandwidth and lower
voltage. The C AZP and C AZN inputs to the limiting amplifier provide an
auto-zero function to effectively cancel any input offset voltage present in
the amplifier.
identify when the input signal has been lost. This information can be fed
back to the Disable input of the device to maintain stability under loss of
signal conditions. Using the V set pin the sensitivity of the level detect can
be adjusted. The C LD input is used to filter the level detect input so that
random noise spikes are filtered out.
