25 mm W I R E L E S S XTR VF 2.4 LPXTR VF 2.4 LP Very Fast Low Power Multichannel TransceivVery Fast Low Power Multichannel Transceiverer DDeessccrriippttiioonn XTR VF 2.4 LP transceiver, pin to pin compatible with Aurel module XTR CYP 2.4GHz and Cypress module CYWM6935 LR 2.4GHz DSSS Radio SoC, represents an extension suitable for data transfer at 1Mbit/sec (from 64Kbit/sec available from previously available modules), with reduced current consumption and wide supply voltage range (from 1.8 to 3.6V), as supplied with an internal switching power supply with programmable start threshold. Due to the high transmission speed, with short burst to send data packet and with the increased supply voltage range, the module is ideally suitable for battery operated applications. It operates in the License Free Industrial, Scientific and Medical (ISM) band at 2.4GHz and it offers a complete radio module solution for integration into existing or new 2.4GHz products. It uses a DSSS (Direct Sequence Spread Spectrum) technique that allows operation in disturbed environments and that reduces the interference caused by traditional narrowband signals. This technique also allows coexistence with Bluetooth and Wi-Fi as well as all other wireless technologies that utilize the 2.4GHz ISM Band. Radio transceiver embeds a PIFA (Planar Inverted F Antenna) and can be connected to a microcontroller and one or more external devices via SPI Interface. This last facility makes possible full transceiver programmability: in particular, possibility is given to set RF channel, data transmission speed and RF radiated power level. RF channels available are 98 (1 MHz wide channels, from 2.400 to 2.497GHz), available, for usage compliant to national requirements, in the ISM band of 2.400 to 2.4835GHz Band. Transmission range is selectable from 16Kbit/sec to 250Kbit/sec according to the used spreading code. It can be increased to 1Mbit/sec if spread spectrum technique is not used. At lower speeds, the Aurel XTR VF 2.4 LP module is radio compatible with Aurel XTR CYP 2.4GHz. Improved capabilities are available. For example, automating packet framing is available to insert number of bytes detail and CRC error control code. ACK packet can be automatically retransmitted.
