STV5715 is intended for 2 heads VCR applications. High performancetechnologyallows very low noise levels (current and voltage), which are frequency independant in all the frequency range. In playback mode a special feature suppresses the DC offset when switching the two channels. Optimized play-back output stage gives to the STV5715 large capability to drive directly a coaxial cable in order to reduce number of external components. Two play-back outputs are availabe : one, dedicated to Chroma processing, is a 60dB voltage amplifier output, the other, dedicatedto Luma processing, is phase opposite signal with a constant AC output level of 200mVPP at 3.8MHz signal.
