SEMICONDUCTOR TECHNICAL DATA
The MC10SX1127 is an integrated limiting amplifier for high
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 2.5Gb/s
range, the high gain limiting amplification of the SX1127 is ideal for high
speed fiber optic applications like SONET/SDM, ATM, FDDI, Fibre

The SX1127 incorporates a programmable level detect function to
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
pin the sensitivity of the level detect
input is used to filter the level detect input so
