The Q5) Evaluation Board has been made for 868MHz operation. This document specifies the usage of the Evaluation Board and suggests some evaluation testbenches. The Evaluation Board is intended for evaluation purposes only. It is not intended for incorporation into an end product. *HWWLQJVWDUWHG To test the Q5) device to its full extent, the following instrumentation should be at your disposal: • • • • • • A +2.7V to +3.3V variable DC voltage supply, and/or a +4.5V to +16V variable DC voltage supply. Dual channel oscilloscope Low frequency generator / digital pattern generator RF signal generator with FSK modulation capability RF Spectrum analyser Bit-error-rate meter (optional) No software is necessary to use the Evaluation Board in Default mode (see Table 1). ETSI document EN 300 220-1 V1.3.1 describes the technical characteristics and test methods for radio equipment to be used in the 433MHz and 868MHz ISM band. A copy of this document can be obtained from the ETSI web-site at KWWSZZZHWVLRUJ. The US Federal Communications Commission (FCC) standard CFR47, Part 15 describes the technical characteristics and test methods for radio equipment to be used in the 902MHz – 928MHz band.

The PCB layout and component placement is shown in Appendix 2. The component list is given in Appendix 3. Selection of standby mode or normal operation mode (transmit/receive) is done by using on-board slideswitch S2 (STBY). Selection of power down mode or standby/transmit/receive mode is done by using on-board slideswitch S3 (PWR_DWN). Setting of transmit/receive mode is done by using on-board slideswitch S4 (TXEN). Selection of normal operating mode or programming mode is done by using on-board slideswitch S5 (CS). The DATA and RF in/out signals are made available at SMA connectors. The CFG_CLK, CFG_DATA, CS, STBY, PWR_DWN, CLK_OUT, C_SENSE, TXEN and DATA signals are also available to an external microcontroller or PC at header J1. :KHQXVLQJKHDGHU-WKHVOLGHVZLWFKHV667%<63:5B':16 7;(1DQG6&6PXVWEHVHWWR+LJK Figure 2 shows the block diagram of the Q5) Evaluation Board. &)*B&/. 9 &)*B'$7$ &6 5 67%< 5 *1' 5 3:5B':1 3RZHU &/.B287 9YROWDJH UHJXODWRU RQRII &B6(16( 7;(1 9 *1' 5 '$7$ *1' 7;(1 3:5B':1 67%< &6 &DUULHU 6HQVH TXEN PWR_DWN STBY CS VDD Q5) CFG_CLK CFG_DATA CLK_OUT C_SENSE DATA RF in/out 50 Ohm '$7$ 5)LQRXW2KP Figure 2.

A +3V voltage regulator is included after connector J4, enabling an input voltage in the range of +4.5V to +16V. &RQQHFWRU-LVDQXQUHJXODWHGSRZHULQSXWDQGYROWDJHUDQJH RQWKLVLQSXWPXVWEHUHVWULFWHGWR9WR9DQGKDYHFRUUHFWSRODULW\. The supply of the Q5) device can be switched on/off by using slideswitch S1. Diode D1 included after connector J4 is for protection against accidental reversal of the power supply polarity. 6XFKDSURWHFWLRQLVQRWLQFOXGHGDIWHUFRQQHFWRU-. The applied 11.0592MHz reference crystal has an overall frequency tolerance (frequency tolerance at 25°C + temperature drift) that does not exceed ±20 ppm in the operating temperature range -20°C to +80°C. The on-chip VCO requires two external inductors L1 and L2. For VCO operation at 868MHz, L1 = L2 = 22nH is optimal. The PLL synthesiser loopfilter is an external single-ended third order lag/lead filter. The PLL filter shown in the circuit diagram is optimised for bit rates up to 76.8 kbit/s. The external 1st IF-filter F1 is a piezoelectric ceramic filter with 330Ω input/output impedance. Center frequency is positioned at 10.7MHz, and 3dB bandwidth is 180kHz. For convenient connection of the differential antenna output/input pins to a single ended antenna or 50Ω test equipment, a differential to single ended matching network is included. This network matches the single ended antenna or 50Ω test equipment impedance at SMA connector J3 to the recommended differential load impedance at the Q5)’s output/input stage. The employed matching network introduces an insertion loss of approximately 2dB at 868MHz. When a carrier is detected in the received channel, the C_SENSE output is +LJK (logic “1”) and status LED D3 is switched on. 'HIDXOWPRGHRSHUDWLRQ The nRF903 device features a pre-programmed Default mode that is available without using the SPI-configuration procedure as described in the nRF903 datasheet. On the Evaluation Board, Default mode can be set by using slideswitches S2 (STBY), S3 (PWR_DWN), S4 (TXEN) and S5 (CS) as shown in Table 1.
