DESCRIPTION
The TMC57750 is a monolithic integrated circuit designed to supply timing signals for the Texas Instruments 4 mm TC255 monochrome CCD image sensor. The TMC57750 supplies both CCD drive signals and
EIA-170 television synchronization signals at standard video rates. It requires a single 5 V supply voltage and a 25-MHz timing crystal or crystal oscillator. The TMC57750 provides the user with several
options including antiblooming frequency selection, external synchronization, fixed electronic shutter selection, electronic auto-iris, and window selection.
The TMC57750 is designed to drive the TC255 CCD image sensor through an intermediary level-shifting device such as the TI TMC57253 serial and parallel driver. It supplies sampling, clamping, and
synchronizing signals for the TI SN76121OFR video processor. The TMC57750 EIA-170 synchronization signals include composite sync, composite blank, and field indicator. The TMC57750 comes in a 64-pin
plastic flat package and is characterized for operation from -20°C to 45°C.
