A TV Horizontal I/C

Abstract

The design of new integrated circuits must be oriented to the cost and flexibility demanded by the function. This paper describes a new I/C which houses the horizontal APC system in only 8 pins while retaining excellent flexibility. Simple, yet sufficient circuits for the RC oscillator and balanced phase detector have all important parameters available externally. A special predriver circuit uses one pin to adjust the output for any type of horizontal driver. By modifying the external circuitry, the TV designer can tailor the I/C to meet a wide range of performance requirements in monochrome and color TV.
