Phase-Locked Loop (PLL) Fundamentals | Analog Devices
Abstract: Phase-locked loop (PLL) circuits exist in a wide variety of high frequency applications, from simple clock clean-up circuits, to local oscillators (LOs) for high performance radio communication links, and ultrafast switching frequency synthesizers in vector network analyzers (VNA). This article explains some of the building blocks of ...
Fundamentals of RS-232 Serial Communications - Analog
Mar 29, 2001 · RS-232 Specifications. RS-232 is a complete standard. This means that the standard sets out to ensure compatibility between the host and peripheral systems by specifying: Common voltage and signal levels. Common pin-wiring configurations. A minimal amount of control information between the host and peripheral systems.
The op amp common-mode rejection ratio (CMRR) is the ratio of the common-mode gain to differential-mode gain. For example, if a differential input change of Y volts produces a change of 1 V at the output, and a common-mode change of X volts produces a similar change of 1V, then the CMRR is X/Y.
DC to DC Buck Converter Tutorial & Diagram | Analog Devices
Nov 29, 2001 · Figure 8 shows a practical circuit using the boost topology formed with the MAX1932. This IC is an integrated controller with an onboard programmable digital-to-analog converter (DAC). The DAC sets the output voltage digitally through a serial link. R5 and R8 form a divider that meters the output voltage.
I2C Primer: What is I2C? (Part 1) | Analog Devices
Sep 2, 2016 · The Inter-Integrated Circuit (I 2 C) bus is a two wire serial interface originally developed by the Phillips Corporation for use in consumer products. It is a bi-directional bus that is easily implemented in any IC process (NMOS, CMOS, bipolar) and allows for simple inter-IC communication. Connections are minimized by using a serial data line ...
I2C Communication Protocol: Understanding I2C Primer, PMBus
These are called System Management Bus (SMBus) and Power Management Bus (PMBus). By definition, Inter-Integrated Circuit (I 2 C)—also known as Inter IC—is a hardware communication protocol that uses synchronous communication with a multi-main, multi-node, and serial communication bus. Synchronous communication means two (or more) devices ...

Dec 29, 2000 · Three common serial data standards, RS-232, RS-422, and RS-485, are described by specification and electrical interface. Cable termination techniques, use of multiple loads, daisy-chaining of RS-232, conversion of RS-232 to RS-485, conversion of RS-485 to RS-232, and RS-232 port-powered RS-485 conversions are described.
Guide to LED Circuit Designs and LED Basics & Operation
Assuming that a single green LED with 10mA forward current should have a constant operating voltage of 5V, the series resistor R V equals (5V -V F,10mA)/10mA = 300Ω. The forward voltage is 2V, as indicated by a graph of typical operating conditions found in the data sheet (Figure 2). Figure 1. Standard red, green, and yellow LEDs have forward ...
