Vitesse Semiconductor Corp. has released a 3.125-Gb/s integrated transimpedance and limiting amplifier with a signal detection feature and photocurrent monitor. The VSC7969 does not require external electrical components in the construction of high-performance optical receivers for SONET/SDH applications. The device operates with a single 3.3-V power supply with maximum power dissipation of 300 mW. A PIN photodiode or APD can be connected and separately biased. The VSC7969 is available in die form and in a 16-pin plastic thin-shrink small-outline package.
