If one inductor is placed so that it has a very short straight trace, the other inductor will not fit in front of its corresponding pin.
Each page is bytes wide. Design and layout is an art form, and never more so than when you are designing an RF circuit.

The Texas Instruments Datahseet family of ultralow power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications.
The preferred method is to route bottom side traces on the opposite side of the CC from the RF outputs.
This will cause the trace for the second inductor to be longer with more bending. In designing circuits using their components, Texas Instruments’ website provides very helpful documentation and design examples.
When pins are located next to each other and have a capacitor associated with each one, these components must be connected individually. For more information on the CC microcontroller, the datasheet can be found at TI.
The current version at the time this article was written is Rev D, dated May 29, The complete file can be obtained from the Worldsens web site. By taking the time apply these techniques, hopefully, it will save you some layout mistakes and reworks, and thus reduce both development time and costs.
However, the trace widths for the filter balun section itself should be as wide as possible without requiring a resize at the pads of datasjeet filter balun components in other words, you should make the traces from the CC to the filter inductors the same width as the CC pads.
The whole memory can be erased using the Bulk Erase instruction, or a sector at a time, using the Sector Erase instruction.
The modem supports various modulation formats and has a configurable data rate of up to kBaud. Note that the humidity sensor is optional and by default it is not build on the WSN node. First it converts the balanced RF signals from the CC into an unbalanced signal. If this is not possible, the trace dataaheet be routed directly below the device, but NOT under the RF pads or filter balun.
Figure 5-Incorrect Figure 6 – Acceptable Figure 7 – Correct Importance of decoupling capacitors to each pin When using the reference design provided by TI, it is important datashest understand that each decoupling component is included for a reason. For this reason, it is very important to keep the component spacing and traces satasheet equal as possible. The effect of having the two sides with uneven layouts is higher harmonics especially the 2nd and 4th as well as reduced output power at the single-ended side of the filter balun.
The RF transceiver is integrated with a configurable baseband modem. Don’t let that stop you, there are still some good articles here!
In this case, if the width is wider than the component pads, datashet trace will have to be reduced just before entering the pad. The memory can be programmed 1 to bytes at a time, using the Page Program instruction. Recommended PCB Layout 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 cc1100 that are not shown in the diagram.
The current design datasheey improvements to eliminate harmonic emission as well as variations based on power settings. The balanced portion of the filter balun is very susceptible to variations between the two sections. Schematic of the WSN board The current version for the CC is CC With a two-layer design, it becomes more complicated to achieve a solid ground.
The digitally controlled oscillator DCO allows wake-up from low-power modes to active mode in less than 6ms. 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 trace width needs to be set based on the thickness of the dielectric and maintained up to the antenna. Layout Resources on the Web.

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. The pin-for-pin and code compatible CC has better spurious response and improved close-in phase noise for adjacent channel performance.
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! A copy of the picture is reproduced below: Table of Contents 1. At the present time Augustthree designs have been published for the CC chip, but the first two are no longer recommended. Figure 3-Incorrect Figure 4-Correct Solid ground plane below the IC and filter balun components Another important aspect of the filter balun layout is the ground plane.
In and ideal world, the components would be right next to each other without any traces required to connect them. What the picture does not show is how the supporting components should be placed and routed.
Because the CC packaging has pins on all four sides, it can be difficult to connect things such as power.
