The circuit is equipped with a ’soft clip’ function. The Video Modulation depth is measured for a 1.0 VCVBS input level, giving modulation depth MDA; then the same measurement is carried out for an input level of 1.5 VCVBS, giving modulation depth MDB. The Peak White Clip is defined as 100*(MDB)/(MBA). 2. The frequency dependent specifications are greatly influenced by the PCB layout in the application. These specifications have all been measured using a Motorola application layout and circuit similarly as shown in Figures 19 and 21. The reference number for ordering this evaluation board is MC44350EVK. –6.0 60 21 Channel Number 24 27 30 33 36 39 42 45 48 51 54 57 60 63 66 69 55 50 45 Typical Performance Maximum Specification Limit 21 Channel Number 24 27 30 33 36 39 42 45 48 51 54 57 60 63 66 69 –8.0 Typical Performance Maximum Specification Limit –4.0 –2.0 0 2.0 4.0 6.0 8.0 Minimum Specification Limit Figure 6.
