		Fixed Video Modulation Index		SEMICONDUCTOR
	These modulator circuits are intended for use in VCRs, satellite receivers,			TECHNICAL DATA
	set±top boxes, video games, etc. An on±chip high speed I2C compatible bus
	receiver is included and is used to set the channel, tuned by a PLL over the
	full range in the UHF bands. The modulator incorporates a sound subcarrier
	oscillator, using a second PLL to derive 4.5, 5.5, 6.0 and 6.5 MHz carrier
	frequencies, selectable by the bus.
	For the sound, either frequency modulation with pre±emphasis or			20
	amplitude modulation (MC44353 only) is possible. A control bit (MC44353			1
	only) is used to select AM sound with positive RF modulation (system L). The

	level of the sound carrier with respect to the vision carrier and the modulation
	depth of both sound and vision may be adjusted by means of the bus. In			PLASTIC PACKAGE

Normally, all VCC lines will come up at the same time.

However, due to the possibility of a Standby VCC to be

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.
