Transceivers in the field of FPGAs: When and why will we use them?

I am recently getting myself into the field of FPGA design and development, and lately I've found myself hearing a lot about transceivers. I tried searching the net for some answers about these components and learn their role in the world of FPGAs…

How does frequency affect the ability to traverse objects in RF transmissions?

Or perhaps, what are the best bands/modulations to choose from if I need to efficiently transmit data in a path with heavy metal obstacles? I need to build a number of devices to periodically transmit short bursts of data in a large storage facility…

Low-power wireless module strategy

I'm designing low-power sensor modules which will be spread over a reasonably small area. The modules are all battery powered and should operate for a decently long time without having to recharge/replace the batteries (the longer the better, think…

Designing my own Bus

This question is further to my previous question: Alternatives to SPI because of EMI. I am toying with the idea of designing my own communication bus. I would be grateful if someone could cast their eye over my preliminary design, and tell me where…

In USB, what is the difference between a PHY and a transceiver?

I understand PHY to be the physical layer of the transceiver protocol stack. At the same time I understand that transceivers are devices that transmit serial data at a very high speed i.e >100Mbps. What I am not sure about is ICs that have PHY in…

How can I fix a dry solder pin in a BGA package?

I am facing problem in a 16-bit transceiver chip, 74LVCHR16245AZQLR, which is a 56-pin BGA package. Its one data pin is not working as expected while all other pins are working OK. The problem pin is only sinking 6 mA of current while all other data…

Must RS-232 devices use the same logic level?

I want to interface a microcontroller with the RS-232 COM port of my PC. My PC uses a 75232G IC, which uses +/-12V logic levels as per some multimeter tests. Currently I'm planning to use the TRS3243ECRHBR IC as the transceiver between the MCU and…

Why are the USB signal pins always swapped on USB bridges?

So I've been looking around for quite some time for a USB<->UART transceiver that has the pins properly ordered. If you'll look at the picture here, you can see that the pin order of the connector is VBUS D- D+ GND and the pins at on the bridge…

How to know (or estimate) the range of a transceiver?

I'm trying to decide between different wireless transceivers, where my main requirement is furthest range for a given frequency band. Is there a way to relate the frequency, data rate, power output, current received/transmitted, etc into a decent…

5 V to 12 V transceiver chip / hardware

I am looking for a way to connect my logic analyzer (an inexpensive Saleae which is intended for 1.8-5V targets) and a couple of other pieces of analysis equipment to a digital source with signals in the 12 V range. I see that there have been a…

J1708 Half Duplex Collision Detection

SAE J1708 is basically an RS485 hardware interface without the typical 120 ohm termination resistors. In typical applications, a half-duplex RS485 transceiver chip is used to connect to the bus. In order to avoid collisions, J1708 protocol rules…

Is there hardware compatibility between CAN 2.0 High Speed, Low Speed and CAN-FD?

I am studying CAN interface hardware for the design of an automotive scanner. So far, I have identified the following types of CAN: CAN 2.0 High-Speed: bit rate up to 1Mbps CAN 2.0 Low Speed: bit rate above 40Kbps up to 125Kbps CAN-FD: bit rates…

Basic CAN-BUS circuit - what does this section do?

I'm currently learning how to make a circuit for CAN-BUS communication and came across the schematics of the Sparkfun CAN-BUS shield for Arduino (can be found here). I'm a little puzzled by this section that shows a 100 ohm resistor and a 560 pF…

Multiplexing a CAN bus

I want to use a small 8 bit microcontroller which has only a single CAN rx/tx, i.e. Atmel 32c1, but in my application I need to be able to send and receive requests from two CAN buses. I have read the datasheet for a particular transceiver,…
