4 / 53 page ![]() —4— CXA1810AQ/AR Pin Description Pin Symbol Pin voltage Equivalent circuit Description No. DC AC Chroma emphasis f0 (center frequency) adjustment. (Refer to item 7 on Description of Operation.) Main emphasis and main de- emphasis time constant. When recording, the emphasized Y signal prior to white/dark clipping is output. Main emphasis and main de- emphasis time constant. Apply an external constant between this pin and Pin 2, as shown below. HPF time constant that forms sub emphasis and sub de- emphasis. Add resistance between this pin and Pin 11. During recording, Y emphasis input. During playback, this signal to the noise canceler is input. Performs diode clamping (sync tip clamping), with the clamp capacitance attached externally. 25µA 150 1 1mA 150 2 4k 100 3 100 4 100 150 5 1 C EMPH CONT 2 MAIN EMPH OUT 3 MAIN EMPH TC 4 SUB EMPH TC 5 EMPH IN Control range: 1.8V to 3.8V 2.05V (sync tip level) 2.05V (when time constant connected) 2.05V (when time constant connected) 2.05V (sync tip level) — 250mVp-p output — — 500mVp-p input 2 3 VG1 11 4 |
