TK15400 Overview
Operating from a single +5 V supply, the TK15400 is a triple video line driver IC that takes standard Y/C analog inputs and provides simultaneous Y/C and posite analog outputs for driving 75 Ω lines. 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 to produce 2 VP-P (typical) into a series 75 Ω resistor and 75 Ω...
