Note 1: All devices are 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by design.

Note 2: NTSC 75% color bar signal applied to video input. CL = 10pF on D9–D0 and LLC. External XTAL.

Note 3: Internal test only. Digital core controls sync level adjustment current to adjust offset in analog signal path. Adjust level is

based on value of sync level as converted by ADC. Digital core switches sourcing or sinking current into VIN1 or VIN2

nodes. Speed of correction (value of current) is controlled through I2C.

Note 4: Filter and ADC performance measured using ADC outputs prior to composite digital demodulation (decoding).

Note 5: Decoded luminance and chrominance specifications measured using entire signal path from video input to digital compo-

nent outputs.

Note 6: VDVDDIO = 1.8V and 3.3V.

Note 7: CB is in pF.
