| ICs for TV AN5422K Deflection-Signal-Processing IC for TV/Display s Overview The AN5422K is an integrated circuit for TV/display deflection-signal-processing circuit. Horizontal oscillation frequency is up to 120kHz. The duty of a horizontal output pulse can be changed by the external bias so that the display is designed easily. 1 2 3 4 5 6 7 8 9 10 11 22 21 20 19 18 17 16 15 14 13 12 0.50.1 4.50.25 0.35 - 0.0 + 0.1 5 Unit : mm 0.90.25 19.10.3 s Features * Noise canceller circuit built-in (with lock-out preventive circuit) * The duty of a horizontal output pulse can be changed by the external bias. * Horizontal oscillation frequency : max. 120kHz * X-ray protector built-in (shutdown) * Vertical drive circuit built-in 6.350.3 1.10.25 3.450.25 3 to 15 7.620.25 22-Pin Shrunk DIL Plastic Package (22-SDIP) s Block Diagram VCC1 22 21 20 19 18 14 GND1 17 16 15 13 12 Ver.
