STPS2045CT 描述
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for external periods may affect device reliabili ty. * All voltage values are referred to VSS pin voltage.
STPS2045CT 特点
The STPS2045CTs VGA section consists of two parts: the Volt- age Controlled Attenuator (VCA) and the Programmable Gain Amplifier (PGA). The gain and gain range of the PGA can be digitally programmed. The combination of these two program- mable elements results in a variable gain ranging from 0dB up to a maximum gain as defined by the user through external connections. The single-ended unity gain input buffer provides predictable high input impedance. The output of the VGA can be used in either a single-ended or differential mode to drive high-performance Analog-to-Digital Converters (ADCs). A sepa- rate power-down pin reduces power consumption.
STPS2045CT 应用
STPS2045CThe STPS2045CT, a pin-compatible replacement for the STPS2045CTMC2302, is a high-speed self-sequencing address genera- tor which supports image manipulations such as rotation, rescaling, warping, filtering, and resampling. It remaps the pixel locations of a target (display) space back into those of a source image space. STPS2045CThe degree and type of image manipula- tion is determined by the remapping selected.
