NOTES: 1. 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.
