Silicore VIDEO IF PROCESSOR FOR B/W TV CD1366CP GENERAL DESCRIPTION The CD1366CP is a silicon monolithic integrated circuit designed for VIF section in B/W television receivers. This IC has functions including video IF amplifier, video low-level detector, RF AGC, IF AGC and no ise ch ancellor. This IC is encapsulated in 14 pin dual in-line package with heat tab. FEATURES z High input sensitivity; TYP. 30dBµ. z It can be used bo th of keyed type AGC and peak type AGC. z It can be operated with the power supply voltage above 7V. z Since the video detector has wide bandwid th, it's suitable for the sound carrier frequency of 4.5, 5.5, 6.0, 6.5 MHz. z As input is differential mode, it can be used with SAW filter. z All function s for VIF stage are provided by th is sing le ch ip IC and this IC will realize reduction of assembly cost as well as reduction of nu mb er of external components.
