SPI Real time clock/calendar Time keeping application

The NXP PCF8523 and PCF2123 are CMOS devices that combine a real-time clock (RTC) and a calendar. Optimized for low power consumption, they operate at a current of less than 100 nA with a 2.0 V power supply, and consume less than 0.2μW of power. The PCF8523 uses an I2C-bus serial interface while t

SPI Real time clock/calendar

General description\nThe PCF2123 is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power applications. Data is transferred serially via a Serial Peripheral Interface (SPI-bus) with a maximum data rate of 6.25 Mbit/s. An alarm and timer function is also available providing the possibili

Low voltage dual 1-5 differential ECL/PECL clock driver

DESCRIPTION The PCK210 is a low skew 1-to-5 dual differential driver, designed with clock distribution in mind. The input signals can be either differential or single-ended if the VBB output is used. The signal is fanned out to 5 identical differential outputs. The PCK210 is specifically designe
