The preferred method is to route bottom side traces on the opposite side of the CC from the RF outputs. For more information on the CC microcontroller, the datasheet can be found at TI. This will obviously make the layout a little more complicated, but extra effort will be appreciated when the circuit performs as expected without troubleshooting and modifications to the PCB.
In and ideal world, the components would be right next to each other without any traces required to connect them. Recommended PCB Dqtasheet for QLP 20 Package TI notes that this diagram is an illustration only and not to scale, and that there are five 10 mil via holes distributed symmetrically in the ground pad under the package that are not shown in the diagram.
Each page is bytes wide.
Schematic of the WSN board The complete file can be obtained from the worldsens web site. The modem supports various modulation formats and has a configurable data rate of up to kBaud.
When pins are located next to each other and have a capacitor associated with each one, these components must be connected individually. The DS’s registration number is a factory-lasered, bit ROM that includes a unique bit serial number, an 8-bit CRC, and an 8-bit family code 01h. In this case, if the width is wider than the component pads, the trace will have to be reduced just before entering the pad. The digitally controlled oscillator DCO allows wake-up from low-power modes to active mode in less than 6ms.
The correct procedure is to route an individual trace from each pin to its associated capacitor.
With extensive capabilities for packet handling, data buffering, burst transmissions, clear channel assessment, and link quality indication, this chip is typically used dataxheet an on-board microcontroller. Conclusion This article, if read in conjunction with the excellent TI application notes for this chip, will make it easier to incorporate the CC into your design.
At the present time Augustthree designs have been published for the CC chip, but the first two are no longer recommended. The versatility of this chip is enhanced by its integrated and highly configurable baseband modem, which supports a number of different modulation formats and data rates.
The CC also provides hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication, and wake-on-radio. For this reason, it is very important to keep the component spacing and traces as equal as possible.
Because the CC packaging has pins on all four sides, datashset can be difficult to connect things such as power. You can spend all this time and money you save here on designing better firmware for the chip and its associated microcontroller – with the versatility available with the CC, this is where the real excitement should be! The trace width needs to be set based on the thickness of the dielectric and maintained up to the antenna.
Layout Resources on the Web. A copy of the picture is reproduced below: Table of Contents 1. Hardcover – pages August datashet Paperback – pages, 2nd edition November 2, This provides us with the ability to offer several options to our clients while using a datasheeet and proven transceiver architecture.
The memory can be programmed 1 to bytes at a time, using the Page Program instruction. Thus, the whole memory can be viewed as consisting of pages, or 1, bytes. While the advice presented here may seem simple, failure to apply these techniques may result in a circuit that does not perform as desired.
The pin-for-pin and code compatible CC has better spurious response and improved close-in phase noise for adjacent channel performance. The current design has improvements to eliminate harmonic emission as well as variations based on power settings. This microcontroller, an ultra-low-power bit RISC mixed-signal processor, is ideal for low power and portable applications.

The current version at the time this article was written is Rev D, dated May 29, SSS Online is proud to present some tricks and hints on this important topic to help you design RF circuits that don’t fall prey to the harmonics, drop out and other bugaboos that can haunt the designer. By using a single trace the pins are no longer isolated from each other. The Texas Instruments MSP family of ultralow power microcontrollers consists darasheet several devices featuring different sets of peripherals targeted for various applications.
As an example, when placing the LPF inductors that connect directly to the CC, it would be better to have both set slightly off from the pins.
This would allow for the traces to be of equal length and shape. Originally developed by ChipCon, this chip has continued as an active TI product following their acquisition of ChipCon in early Layout Resources from Pegasus Technologies. Second it provides a low pass filter. If this is not possible, the trace should be routed directly below the device, but NOT under the RF pads or filter balun. Don’t let that stop you, there are still some good articles here!
