Low-Jitter Clock for High-Speed Data Converters

Figure 1 illustrates the simplified block diagram of a typical high-speed data converter system. The system consists of a bandpass filter, ADC, high-frequency clock, high-speed storage device, and post processing unit. Aside from the MAX104, the high-frequency clock plays a significant role in determining the accuracy of a high-speed data...
visible optical link for RS-232C

The design in Figure 1 is a visible optical link for those who need to see the transmitted data. An isolation figure of more than 5000V is a bonus. Tests of the system used the COM input of a data-acquisition system, as well as a standard PC`s COM port. The MC1489 converts the RS-232C data to TTL signals. A 7404 gate then inverts the signal. The...
PC monitors two-way RS-232 transmission

The method in Figure 1a needs no access or knowledge of the communicating devices. A C program opens two COM ports and installs interrupt-service routines for IRQ4 and IRQ3. Upon the reception of an interrupt, the routine stores a byte in a common circular buffer with the COM identifier and error flags. The main program displays the contents of...
3.3V & 5V Regulator to Run Computer & RS232

The circuit consists of two sections, one being a DC/DC converter and the other being a pair of dual N-channel MOSFETs and their associated high-side drivers that effectively form a DPDT switch.
RS232 Interface Circuits

The rapid, widespread use of 3.3V logic circuits complicates the selection of RS232 interface circuits. The optimum choice of an interface circuit should be based upon several application dependent factors: 1) Logic circuitry connected to interface chip 2) Power supply voltages available 3) Power consumption constraints 4) Serial...
RS232/RS485 Multiprotocol Transceiver

The RS232 transceiver supports both RS232 and EIA-562 standards, whereas the RS485 transceiver supports both RS485 and RS422 standards. The logic input (MODE) selects between RS232 and RS485 modes. With three additional control logic inputs (RXEN, DXEN and ON), the LTC1387 adapts easily, as shown in Table 1, to various communications...
RS232 Connections wiring up

While the normal PC hardware might well run with just Tx, Rx and Ground connected, most driver software will wait forever for one of the handshaking lines to go to the correct level. Depending on the signal state it might sometimes work, other times it might not. The reliable solution is to loop back the handshake lines if they are not used. .
RS-232 Powered Temperature Sensor

A state-of-the-art silicon temperature sensor like MAX6577 measures a remote temperature far from the host system. The temperature sensor converts this temperature into a square wave with a frequency proportional to the absolute temperature of its package, while drawing little supply current from the power source. The amplitude of the output...
RS485-like multi-drop bus

PBUS is an RS485-like multi-drop bus for interconnecting PIC and other microcontroller-driven devices. Protocol and software is written by Jap. Just include a separate pbus library file into your project and add your command handlers for the specific device in a few lines. .
RS232 Transceivers circuits

Hand held computers are rapidly moving to 3V logic to save power. Yet higher voltage buses are still utilized elsewhere in the system for display driving and other functions. The LT1330 is functionally equivalent to the LT1237 but operates from 5V with a separate logic supply to interface directly with 3V logic.
One-Wire Serial Bus Carries Isolated Power And Data

Medical and industrial applications often require galvanic isolation of 2500 V ac or higher for the safety of patients and equipment operators. The isolation barrier conveys not only power to the sensing element, but also data to or from that element. Each data signal crossing the barrier-requires isolation. Consequently, designers can typically s .
