SHAOXING SILICORE TECHNOLOGY CO.,LTD www. Silicore. com. cn CHMC 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 noise chancellor. 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 both 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 bandwidth, it's suitable for the sound carrier z As input is differential mode, it can be used with SAW filter. z All functions for VIF stage are provided by this single chip IC and this IC will realize reduction of assembly cost as well as reduction of number of external components.
