Implementing Color Reproduction for TC236 CCD Sensor Using the TMS320C2xx DSP
Texas InstrumentsThe Charge-Coupled Device (CCD) sensor is widely used in many video applications such as scanners digital cameras video camcorders etc. In these video systems a processor or hardware circuit processes the CCD raw data before displaying or implementing other image processing algorithms. The process of producing color data from the CCD raw data is called color reproduction.In this applicatio
Low-Power Support Using Texas Instruments SN74SSTV16857 and SN74SSTV16859
Texas InstrumentsThe Texas Instruments SN74SSTV16857 and SN74SSTV16859 registers support the low-power mode of the DDR-DIMM. This application report explains the low-power mode and the features of the registers that support the low-power mode. Also the considerations that the system designer must be aware of when implementing the low-power state of a registered memory module are explained. The sequence that must

Controlling Output Ripple & Achieving ESR Independence in Constant On-Time (COT) Regulator Designs (Rev. A)
Texas InstrumentsOf all the voltage regulator control strategies ever devised, the hysteretic regulator is probably about the simplest. This control methodology simply turns a switch on when the output voltage is below a reference and turns the switch off when the output rises to a slightly higher reference. The output ripple is therefore a direct function of the difference between the upper and lower reference threshold, the hysteresis amplitude. It’s hard to imagine something much simpler and, as usual, with simplicity comes performance shortcomings.
Optimizing OMAP3630 BOOT Sequence Using the TPS65023-Q1 (Rev. A)
Texas InstrumentsThe TPS65023-Q1 multi-rail power-supply integrated circuit (IC) realizes all necessary features to supply the OMAP3630 processor. The TPS65023-Q1 device is an integrated power-management IC (PMIC). The device is suited for applications powered by one Li-Ion or Li-Polymer cell requiring multiple power rails. The TPS65023-Q1 device provides three highly-efficient 1500-mA step-down DC-DC converters
