cmt2210lw rev 0.8 | page 12 / 20 www. hoperf .com 5.4.3 rssi the subsequent multistage i/q log amplifiers enhance the output signal from if filter before it is fed for demodulation. rece ive signal strength indicator (rssi) generators are included in both log amplifiers which produce dc voltages that are directly pro portional to the input signal level in both of i and q path. the resulting rssi is a sum of both these two paths. extending f rom the nominal sensitivity level, the rssi achieves dynamic range over 66 db. the cmt2210 lw integrates a patented dc - offset canc ellation engine. the receiver sensitivity performance benefits a lot from the novel, fa st and accurate dc - offset remov al implement ation . 5.4.4 sar adc the on - chip 8 - bit sar adc digitalizes the rssi for ook demodulation. 5.4.5 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 crystal should be used with appropriate loading capacitors (c2 and c3 in figure 9 of page 9 ). the values of the 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 desired frequency . c l = 1 1 c 2 1 c 3 + + c parasitic the parasitic capacitance is constituted by the input capacitance and pcb tray cap acitance. 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 re commended to have a peak - to - peak swing in the range of 300 mv to 700 mv and ac - coupled to the xin pin. 5.4.6 frequency synthesizer a fractional - n frequency synthesizer is used to generate the lo 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 m hz reference clock provided by the crystal oscillator or the external clock source, i t can generate receive frequ enc ies of 315 and 433.92 mhz with a frequency resolution of 24.8 hz. the vco always operates at 2x of lo frequency. a high q (at vco frequenc y) tank inductor should be chosen to ensure the vco oscillates 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 les s spurious emission. the recommended vco inductors for different lo frequency bands are shown as bellow. table 10 . vco inductor for 315/433.92 mhz frequency band lo frequency band (mhz) 315 433 .92 vco inductor (nh) 33 22 multiple subsystem calibrations are performed dynamically to ensure the frequency synthesizer operates reliably in any workin g conditions. 5.5 operation states a s the cmt2210 lw is operating in duty cycle receive mode, the device will go through the states shown as the figure below after
