TK15409 Overview
Operating from a single +5 V supply, the TK15409 is a video line driver IC that takes standard Y and C analog inputs and provides a posite analog output for driving 150 Ω loads (75 Ω resistor and 75 Ω cable load). Internal summing of the Y and C inputs is performed to produce the posite video output. The luminance (Y) input is clamped at 1.25 V and amplified 6 dB;.
