... Fast turnaround times, along with the support for data rates to 33.6Kbps, make the transceiver suitable for a wide range of applications. Housed in a compact through-hole package, the transceiver requires no tuning or external RF components (except antenna), allowing for straightforward application, even by engineers lacking previous RF experience ...

... The transceiver has an on-board voltage regulator that regulates the internal VCC to 3.0V. This allows a wide operating voltage range of 2.7V to 13V. At 2.7V, the internal regulator acts as a saturated switch, directly passing voltage through to the internal electronics. The PDN pin can be used to put the transceiver into a low-current sleep mode (<50uA). 10.7MHz 10 ...

... The transmitter is designed to give an average deviation of 110kHz with a 5V square wave input possible to successfully modulate the transceiver with a level as low as 3 volts; however, the reduced carrier deviation will cause a slight loss in receiver sensitivity and 20% increase in settling times. ...

... Interference can manifest itself in many ways. Low-level interference will produce noise and hashing on the output and reduce the link’s overall range. Thanks to the capture properties system, the transceiver will still function when an intended signal is present at a higher level than the interference. ...

... This will invalidate the timing parameters and may cause illegal emissions from the transceiver. 3. Required transition interval. This is the maximum amount of time that can elapse without a transition on the TX data pin always important to think of data in both the analog and the digital domain. ...

... Switch to transmit mode The transceiver is placed in transmit mode by bringing TXEN high and RXEN low. The PDN pin must be open or pulled to VCC. Once the transceiver is placed in transmit mode, the synthesizer will begin trying to lock. 2) Wait for transmitter to stabilize This step is necessary to allow the transmitter time to lock and stabilize ...

... The procedure here is protocol-dependent but to illustrate, let’s consider the packet format outlined above being sent to a UART. A UART interprets the start- bit of a byte as a 1-0 transition. When the incoming data is 101010 or hash... it is hard to actually find the start bit. This problem is solved by the UART Sync Byte. ...

... Fortunately, because of the care taken by Linx in the layout of the module’s PCB, integrating a TR-XXX-SC-PA transceiver into your design is very straightforward. By adhering carefully to a few basic design and layout rules, you can enjoy a trouble-free path to RF success. Figure 8 shows the suggested PCB footprint for the TR-XXX-SC-PA. ...

... Keep the antenna away from other metal components, particularly large items like transformers, batteries, and PCB tracks and ground-planes. The space around the antenna can be as important as the antenna itself. 3. The ground-plane acts as a counterpoise, forming, in essence, a 1/2-wave dipole ...

... LEGAL CONSIDERATIONS The TR-916-SC-PA module has been previously tested and received certification as a modular product from the FCC. No further testing of the module is necessary when compliant antennas are employed. The pre-certified status of the module is valid only if all of the following are observed: • No modifications to the module may be made. ...
