HD and SD video amplifiers eliminate external circuitry

ON Semiconductor has launched high-performance video amplifiers for High-Definition (HD) and Standard-Definition (SD) applications.

Each device contains three amplifier channels featuring a 6th-order Butterworth reconstruction filter to simplify external circuitry and enhance response at standard frequencies.

The NCS2563 HD amplifier has a 3dB bandwidth of 32MHz, while the NCS2553 has a 3dB bandwidth of 8MHz for use in SD systems.

Both devices feature internal transparent clamps for AC-coupled signals, as well as integrated gain-setting resistors, to reduce the need for external components in the video circuit. The NCS2563 also provides an integrated level shifter. Both devices support AC- or DC-coupled outputs of 150Ω impedance.

 

FEATURES Single, 5V power supply 6dB gain per channel Support for RGB and component video SOIC-8 packages

APPLICATIONS Broadcast studio equipment Professional video systems High-end consumer video HDTV equipment Security systems
