7 / 22 page  —7— CXA1812Q ∗Externally applied voltage Pin Symbol Pin Equivalent circuit Description No. voltage 23 25 24 26 27 29 28 30 YIN1 YIN2 INSEL GND CIN1 CIN2 Y/VSEL YOUTGND 2.5 V (Sync tip) 0 V 0 V ∗ — 0 V 0 V ∗ 1100 GND VCC 1µ 40µ 23 25 150 GND VCC 20µ 20µ 24 Video input Y signal inputs. Coupled by means of a capacitor; in order to keep clamp error to a minimum, keep the input impedance as low as possible. Control input for switching between signals input from Pins 23 and 25 and from Pins 27 and 29. Low (0 to 0.8 V) : signals at Pins 23 and 27 are selected High (2 V to VCC) : signals at Pins 25 and 29 are selected GND other than the 75 Ω driver. Video input chroma signal inputs. Coupled by means of a capacitor within the IC. Inputting a signal of –0.3 V or less may lead waveform distortion. Control input for switching the output signal format for Pin 19. Pin 19 output Pin 21 output Low : Y signal Chroma signal High : Composite High impedance video signal Low (0 to 0.8 V) High (2 V to VCC) Y 75 Ω driver GND. 0.5Vp-p 2.5V 314mVp-p 143mVp-p Same as for Pin 7. — — Same as for Pin 6. |
