Description PAL-COLOR SUBCARRIER GENERATOR
Datasheet SN28837 DatasheetSN28838 Datasheet (PDF)

• 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 characteriz.

1/2-INCH PAL TIMER

SN28837 1/2-INCH PAL TIMER SOCS031B – JULY 1991 • PAL-Timing Operation • Solid-State Reliability • Color and Monochrome Operation • Five Selectable-Antiblooming Modes • Variable-Integration-Time Option • Surface-Mount Package • Clamp-Pulse Select Option • Horizontal and Vertical Resets for External Synchronization description The SN28837 is a monolithic integrated circuit designed to supply timing signals for the Texas Instruments (TI™) 8-mm-diagonal TC276 (PAL color) and TC277 (PAL monochrome) CCD image sensors. The SN28837 supplies both CCD-drive signals and PAL-television synchronization signals at standard video rates. It requires a single 5-V supply voltage and a 13.37-MHz crystal-oscillator input. The SN28837 provides the user with several options including multiple antiblooming modes, variable-integration time, external synchronization, clamp-pulse selection, and delayed horizontal transfer.
