MC10SX1126

The MC10SX1126 is an integrated limiting amplifier for high frequency fiber optic applications. The MC10SX1126 interfaces directly to the transimpedance amplifier of a typical optical to electrical conversion portion of a fiber optic link. With data rate capabilities in the 1.25Gb/s range, the high gain limiting amplification of the SX1126 is ideal for high speed fiber optic applications like SONET/SDM, ATM, FDDI, Fibre Channel or Serial Hippi. The MC10SX1126 is functionally and pin compatible to the Signetics SA5225 with a significantly higher bandwidth. The CAZP and CAZN inputs to the limiting amplifier provide an auto-zero function to effectively cancel any input offset voltage present in the amplifier.

The MC10SX1126 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 MC10SX1126 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.

The MC10SX1126 is compatible with MECL10H logic levels.
