Description

The SN28835 is a monolithic integrated circuit designed to supply timing signals for the Texas Instruments (TIE) 8-mm TC242/TC244 color and TC243/TC245 monochrome CCD image sensors.The SN28835 supplies both CCD-drive signals
and NTSC-television synchronization signals at standard video rates. It requires a single 5-V supply voltage and a 14.318-MHz crystal-oscillator input. The SN28835 provides the user with several options including multiple antiblooming modes, variable-integration time,external synchronization, and delayed horizontal transfer.

The SN28835 is designed to drive the CCD image sensor through intermediary level-shifting devices such as the TI TMS3473B parallel driver and the SN28846 serial driver. It also supplies sample-and-hold signals for the TI TL1593 3-channel sample-and-hold circuit and multiplex signals for the TI TL1051 video preprocessor. The SN28835 NTSC synchronization-signal outputs include composite sync, composite blank, clamp, subcarrier,subcarrier delayed by 90 degrees, and burst flag.

The SN28835 is supplied in a 44-pin plastic flat package and is characterized for operation from 20°C to 45°C.
