QM30-26R-CFI Datasheet In a strong signal environment, the LNA can be shut down by applying OV to pin 5. The result is that the LNA gain decreases from a nominal of +18dB to -19dB. The current in the LNA decreases t0 1mA. In addition, the input lP3 for the LNA increases from -6dBm to +5dBm, and for the downconverter from -11dBm to -7.5dBm. QM30-26R-CFI Price The digital window watchdog timer, U5020M, is a CMOS integrated circuit. In applica- tions where safety is critical, it is especially important to monitor the microcontroller. Normal microcontroller operation is indicated by a cyclically transmitted trigger signal, which is received by a window watchdog timer within a defined time window. A missing or a wrong trigger signal causes the watchdog timer to reset the microcon- troller. The lC is tailored for microcontrollers which can work in both full-power and sleep mode. With an additional voltage monitoring (power-on reset and supply voltage drop reset), the U5020M offers a complete monitoring solution for microsystems in automotive and industrial applications.

D3479, MARCH 199 signal designations In both Figures l and 2, the polarity indicators (1- ) indicate that the associated input or output is active-low with respect to the function shown inside tne symbol and the symbols are the same in both figures. The signal designations in Figure l agree with the indicated internalfunctions based on active-low data and are for use with the logic functions and arithmetic operations shown in Table l. The signal designations have been changed in Figure 2 to accommodate the logic functions and arithmetic operations for the active-high data given in Table 2. |
