Video signal system RGB signals input to Pins 1, 3 and 5 is synchronous clamped by the clamp pulse input from Pin 13. This RGB signals are mixed in the ratio of 0.6G + 0.3R + 0.1B, and Y signal is generated. The high frequency component is pulled out from a Y signal through a differential circuit, and the amplitude is varied according to the gain control circuit. The selecting of gain control and differential circuit time constant is performed by the DC voltage input from Pin 12. Gain controlled signal is output from Pin 15 after amplitude limited from a limiter circuit. At the same time, its signal is added to RGB signals input to Pins 1, 3 and 5, and then is output from Pins 17, 19 and 21. Sharpness Min.

Synchronous system The sync on green signal input to Pin 7 is synchronous separated by the sync separation circuit after diode clamped, and is output from Pin 14 as a positive polarity pulse. The input signal is not sync on green signal, video portion is sliced and then is output as a positive polarity pulse. –9– CXA2093S Example of Representative Characteristics F0_GAIN control characteristics 7 6 GOUT output gain [dB] 5 4 3 2 1 0 0 1 2 3 F0_GAIN applied voltage [V] 4 5 Frequency characteristics 2 0 Output gain [dB] –2 –4 –6 –8 1 10 Input frequency [MHz] 100 300 – 10 – CXA2093S Package Outline Unit: mm 22PIN SDIP (PLASTIC) + 0.1 0.05 0.25 – 12 + 0.4 19.2 – 0.1 22 + 0.3 6.4 – 0.1 1 1.778 11 0.5 ± 0.1 + 0.15 0.9 – 0.1 + 0.15 3.25 – 0.2 0.51 MIN + 0.4 3.9 – 0.1 7.62 0˚ to 15˚ Two kinds of package surface: 1.All mat surface type. 2.All mirror surface type.
