CY7C269-25WI Datasheet:Black level clamping of the video signal is carried out directly on the AC coupled input signal into the high impedance preamplifier input, thus eliminating the need for additional clamp capacitors. Horizontal and vertical blanking of the outputs is provided. Vertical blanking is optional and its duration is register programmable. The IC is packaged in an industry standard 24-lead DIP molded plastic package.CY7C269-25WI Suppliers:The Modulation Selection Table defines the possible spread spectrum options. The optimal setting should minimize system EMI to the fullest without affecting system performance. The spreading is described as a percentage deviation of the center frequency. (Note: The center frequency is the frequency of the external reference input on CLKIN, pin1).CY7C269-25WI On stock:Digital thermometer measures temperature in 0.5C increments (accuracy 1.0C) Built-in real-time clock (RTC) and timer has accuracy of 2 minutes per month from 0C to 45C Automatically wakes up and measures tem- perature at user-programmable intervals from 1 to 255 minutes Logs up to 2048 consecutive temperature measurements in protected nonvolatile (NV) memory Records a long-term temperature histogram with 2.0C resolution Programmable temperature-high and tem- perature-low alarm trip points Records up to 24 time stamps and durations when temperature leaves the range specified by the trip points 512 bytes of general-purpose read/write NV memory Typical lifetime more than 9 years Communicates to host with a single digital signal at 14.1kbits or 125kbits per second using 1-Wire® protocolNotes: 1. This parameter is guaranteed but not tested on Propagation Delays. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. The MAX961CMAX964/MAX997/MAX999 are low-power, ultra-high-speed comparators with internal hysteresis. These devices are optimized for single +3V or +5V operation. The input common-mode range extends 100mV Beyond-the-Rails™, and the outputs can sink or source 4mA to within 0.52V of GND and V CC . Propagation delay is 4.5ns (5mV overdrive), while sup- ply current is 5mA per comparator. The IXDN404/IXDI404/IXDF404 is comprised of two 4 Ampere CMOS high speed MOSFET drivers. Each output can source and sink 4A of peak current while producing voltage rise and fall times of less than 15ns to drive the latest IXYS MOSFETs & IGBT's. The input of the driver is compatible with TTL or CMOS and is fully immune to latch up over the entire operating range. A patent-pending circuit virtually eliminates CMOS power supply cross conduction and current shoot-through. Improved speed and drive capabilities are further enhanced by very low, matched rise and fall times. The AD536A will compute the rms of both ac and dc signals. If the input is a slowly-varying dc signal, the output of the AD536A will track the input exactly. At higher frequencies, the average output of the AD536A will approach the rms value of the input signal. The actual output of the AD536A will differ from the ideal output by a dc (or average) error and some amount of ripple, as demonstrated in Figure 4. |
