• Solid-State Reliability • Surface-Mount Package description The SN28838 is a monolithic integrated circuit designed to interface with the SN28837 PALtiming generator in order to generate the PAL-color timing signals.
It receives inputs from the SN28837 and a 17-MHz oscillator and outputs the PAL-color subcarrier, color subcarrier delayed by 90 degrees, and burst-color-subcarrier signals, which are all 4.
43-MHz outputs.
The SN28838 is supplied in a 16-pin surfacemount package and is characterized for operation from 0°C to 40°C.
