DESCRIPTION

38 digital supply voltage 5

39 digital ground 5

40 not connected

41 digital supply voltage 6

42 digital ground 6

43 not connected

44 Crystal oscillator input (from crystal). If the oscillator is not used, this pin should be connected

to ground.

45 Crystal oscillator output (to crystal).

46 not connected

47 Clock Reference signal. This is the clock qualifier for DIG-TV2 compatible signals.

48 Line-Locked Clock. This is the 27 MHz master clock for the encoder. The I/O direction is set

by the CDIR pin.

49 digital supply voltage 7

50 Clock direction. If the CDIR input is HIGH, the circuit receives a clock and optional CREF

signal, otherwise if CDIR is LOW CREF and LLC are generated by the internal crystal

oscillator.

51 digital ground 7

52 Lower reference voltage 1 input for the RGB DACs, connect to VSSA.

53 Upper reference voltage 1 input for the RGB DACs, connect via 100 nF capacitor to VSSA.

54 Analog supply voltage 1 for the RGB DACs.

55 Analog output of the BLUE component.

56 not connected

57 Analog supply voltage 2 for the RGB DACs.

58 Analog output of the GREEN component.

59 not connected

60 Analog supply voltage 3 for the RGB DACs.

61 Analog output of the RED component.

62 not connected

63 Current input for RGB amplifiers, connected via 15 kΩ resistor to VDDA.

64 Analog supply voltage 4 for the Y/C/CVBS DACs.

65 not connected

66 not connected

67 Analog ground for the DACs.

68 Current input for the Y/C/CVBS amplifiers, connected via 15 kΩ resistor to VDDA.

69 Analog output of the chrominance signal.

70 Analog supply voltage 5 for the Y/C/CVBS DACs.

71 Analog output of the luminance signal.

72 Analog supply voltage 6 for the Y/C/CVBS DACs.

73 Analog output of the CVBS signal.
