| NTE1593 Integrated Circuit Colot TV VIR Processor Description: The NTE1593 is designed for automatic adjustment of the color saturation and tint of color television receiver. Functions: D Identification of line 19 and the detection of the presence of a VIR signal D The development of dc color-controlling voltage by processing the VIR portion of the receiver's simulated blue drive signal D The development of dc tint controlling voltage by processing the VIR portion of the receiver's demodulated R-Y signal Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14.4V LED Drive Current, ILED . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20mA Power Dissipation (TA = +65C), PT . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 600mW Operating Temperature Range, Topt . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -10 to +65C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +125C Electrical Characteristics: (TA = +25C, VCC = 12V unless otherwise specified) Parameter Current Drive Output Voltage of C l Control Stage Color C t l St Symbol ICC V5H V5L V5H V5L Output Voltage of Ti t Control Stage Tint C t l St V6H V6L V6H V6L Differential Voltage Gain of Color Control Stage Differential Voltage Gain of Tint Control Stage GVD1 GVD2 VIR: ON RL = 10k VIR: OFF, Manual VIR: ON VIR: OFF, Manual LED OFF VIR: ON High Level Low Level High Level Low Level High Level Low Level High Level Low evel Input: Pin 3 to Pin 4 Output: Pin 5 Input: Pin 4 to Pin 9 Output: Pin 6 Test Conditions Min - 10 - - - 10 - - - - - Typ Max Unit 21 11.2 0.5 10.7 0 11.4 0.3 10.7 0 40 3.4 35 - 1.0 - - - 1.0 - - - - mA V V V V V V V V dB dB Pin Connection Diagram VCC Variable Y + (B - Y) Color Sample & Hold Reference Sample & Hold Color Saturation Control Output Tint Control Output GND R - Y Input 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 Vert Sync Input (Positive Going) Vert Sync Input (Negative Going) Horiz Flyback Pulse Input Chroma Pulse Width Adjust Composite Video Input (Negative Going Sync) Composite Video Input (Positive Going Sync) LED Indicator Tint Sample & Hold 16 9 .260 (6.6) Max 1 8 .785 (19.9) Max .300 (7.62) .200 (5.08) Max .245 (6.22) Min .100 (2.54) .700 (17.7) |
