cmt2210/17aw rev 1. 3 | page 16 / 28 www. hoperf .com 5.5.5 crystal oscillator the crystal oscillator is used as the reference clock for the pll frequency synthesizer and system clock for the digital bloc ks. a 26 mhz crystal should be used with appropriate loading capac itors (c2 and c3 in figure 10 of page 11 ). the values of t he loading capacitors depend on the total load capacitance c l specified for the crystal. the total load capacitance seen between the xin and xout pin should equal c l for the crystal to oscillate at 26 mhz. c l = 1 1 c 2 1 c 3 + + c parasitic the parasitic capacitance is constituted by the input capacit ance and pcb tray capacitance . the esr of the crystal should be within the specification in order to ensure a reliable start - up. an external signal source can easily be used in place of a conventional xtal and should be connected to the xin pin. the incoming clock signal is recommended to have a peak - to - peak swing in the range of 300 mv to 700 mv and ac - coupled to the xin pin. 5.5.6 frequency synthesizer a fractional - n frequency synthesizer is used to generate the l o frequency for the down conversion i/q mixer. the frequency synthesizer is fully integrated except the vco tank inductor which enables the ultra low - power receiver system design. using the 26 mhz reference clock provided by the crystal oscillator or the e xternal clock source, i t can generate any receive frequency between 300 to 480 mhz with a frequency resolution of 24.8 hz. the vco always operates at 2x of lo frequency. a high q (at vco frequency) tank inductor should be chosen to ensure the vco oscilla tes at any conditions meanwhile burns less power and gets better phase noise performance. in addition, properly layout the inductor matters a lot of achieving a good phase noise performance and less spurious emission. the recommended vco inductors for diff erent lo frequency bands are shown as bellow. table 13 . vco inductor for 315/433.92/ 868.35 /915 mhz frequency band lo frequency band (mhz) 315 433 .92 868.35 915 vco inductor for qfn16 package (nh) 33 22 3.9 3.9 vco inductor for sop16 package (nh) 27 15 -- -- multiple subsystem calibrations are performed dynamically to ensure the frequency synthesizer operates reliably in any workin g conditions. 5.5.7 lposc an internal 1 khz low power oscillator is integrated in the cmt 2210/ 17aw . it generates a clock to drive the sleep timer to periodically wake the device from sleep state. the sleep time can be configured from 3 to 134,152,192 ms (more than 37 hours ) when the device works in duty - cycle receive mode. since t he frequency of the lposc d rifts when the temperature and supply voltage change, it is automatically calibrated during the pup state, and is periodically calibrated since then. the calibration scheme allows the lposc to maintain its frequency tolerance to less than 1%. 5.6 operation mode an option ?duty - cycle on - off? on the rfpdk allows the user to determine how the device behaves. the device is able to work in two operation modes, as shown in the figure below.

cmt2210/17aw rev 1. 3 | page 19 / 28 www. hoperf .com 5.9 easy duty - cycle configurations when the user wants to take the advantage of maintaining the highest system stability and performance, and the power consumption is not the first concern in the system, the easy configuratio n can be used to let the device to work in the duty - cycle mode without complex calculations, the following is a good example: rx t = rx time (1000 ms) rx state tx data sleep, xtal and tune t = sleep time (3 ms) + xtal stabilizing time (310 us) + tuning time (300 us) = 3.61 ms t = packet length (72 ms) a missed packet two missed packets data ( dout pin) output data corrupted output data corrupted time figure 16 . tx and rx relationship of easy configuration in this example, the tx device transmits the data at 1.2 ksps and there are 60 symbols in one data packet. thus, the packet length is 50 ms. the user can do the following: ? set the sleep time to the minimum value of 3 ms. ? set the rx time to 1 second which is much longer than the packet length. ? let the tx device to send out 3 continuous data packets in each transmission. because the sleep time is very short, the non - receiv e time is only about 3. 61 ms (the sum of the sleep time, xtal stabilizing time and the tuning time), which is much shorter than the packet length of 50 ms . therefore, this non - receive time period will only have a change to corrupt no more than 2 packets receiving. during the non - receive time period , the d out p in will output logic 0. because the rx time is very long, and 3 continuous data packets are sent in each transmission, there is at least 1 packet that can be completely received by the device and sen t out via the dout p in with no corruption. the exte rnal mcu will only need to observe the dout p in status to perform data capturing and further data processing. if the system power consumption is a sensitive and important factor in the application, the precise configuration can be used . also, based on the duty - cycle receiv e mode, the ?wake - on radio? technique allows the device to even save more power. for the precise duty - cycle configurations and the use of wake - on radio, please refer to the ?an108 cmt2210/ 17aw configuration guideline ? . 5.10 the nrsto by default, an active low reset signal is generated by the internal por and output via the nrsto pin. it can be used to reset th e external mcu if it is required.
