#:Control v oltage = +2.8v LMD-400-R is equipped with an internal PLL frequency synthesizer as shown in Figure 1. The operation of the PLL circuit enables the VCO to oscillate at a stable frequency. Transmission frequency is set externally by the controlling IC. LMD-400-R has control terminals (CLK, LE, DATA) for the PLL IC and the setting data is sent to the internal register serially via the data line. Also LMD-400-R has a Lock Detect (LD) terminal that shows the lock status of the frequency. These signal lines are connected directly to the PLL IC through a 2 k resistor. The interface voltage of LMD-400-R is 2.8 V, so the control voltage must be the same. LMD-400-R comes equipped with a Fujitsu MB15E03SL PLL IC. Please refer to the manual of the PLL IC. The following is a supplementary description related to operation with LMD-400-R. In this description, the same names and terminology as in the PLL IC manual are used, so please read the manual beforehand. OG_LMD-400-R-C_v12e 10 Circuit Design, Inc. OPERATION GUIDE
. How to calculate the setting values for the PLL register
-- Equation 1 The PLL IC manual shows that the PLL frequency setting value is obtained with the following equation. fvco = [(M x N)+A] x fosc / R fvco : Output frequency of external VCO M: Preset divide ratio of the prescaler (64 or 128) N: Preset divide ratio of binary 11-bit programmable counter (3 to 2,047) A: Preset divide ratio of binary 7-bit swallow counter (0 A 127 A<N)) fosc: Output frequency of the reference frequency oscillator R: Preset divide ratio of binary 14-bit programmable reference counter (3 to 16,383) With LMD-400-R, there is an offset frequency (foffset) 21.7 MHz for the transmission RF channel frequency fch. Therefore the expected value of the frequency generated at VCO (fexpect) is as below. fvco = fexpect = fch foffset
---- Equation 2 The PLL internal circuit compares the phase to the oscillation frequency fvco. This phase comparison frequency (fcomp) must be decided. fcomp is made by dividing the frequency input to the PLL from the reference frequency oscillator by reference counter R. LMD-400-R uses 21.25 MHz for the reference clock fosc. fcomp is one of 6.25 kHz, 12.5 kHz or 25 kHz. The above equation 1 results in the following with n = M x N + A, where n is the number for division. fvco=n*fcomp ---- Equation 3 n = fvco/fcomp ---- Equation 4 note: fcomp = fosc/R Also, this PLL IC operates with the following R, N, A and M relational expressions. R=fosc/fcomp ---- Equation 5 N = INT (n / M) ---- Equation 6 A = n - (M x N) ---- Equation 7 INT: integer portion of a division. As an example, the setting value of RF channel frequency fch 458.000 MHz can be calculated as below. The constant values depend on the electronic circuits of LMD-400-R. Conditions:
Channel center frequency:
Constant: Offset frequency:
Constant: Reference frequency:
Set 12.5 kHz for Phase comparison frequency and 64 for Prescaler value M fch = 458.000 MHz foffset=21.7 MHz fosc=21.25 MHz The frequency of VCO will be fvco = fexpect = fch - foffset = 458.000 21.7 = 436.300 MHz Dividing value n is derived from Equation 4 n = fvco / fcomp = 436.300 MHz/12.5 kHz = 34904 Value R of the reference counter is derived from Equation 5. R = fosc/fcomp = 21.25 MHz/12.5 kHz = 1700 Value N of the programmable counter is derived from Equation 6. N = INT (n/M) = INT(34904/64) = 545 Value A of the swallow counter is derived from Equation 7. A = n (M x N) =34904 64 x 545 = 24 The frequency of LMD-400-R is locked at a center frequency fch by inputting the PLL setting values N, A and R obtained with the above equations as serial data. The above calculations are the same for the other frequencies. Excel sheets that contain automatic calculations for the above equations can be found on our web site
(www.circuitdesign.jp). The result of the calculations is arranged as a table in the CPU ROM. The table is read by the channel change routine each time the channel is changed, and the data is sent to the PLL. OG_LMD-400-R-C_v12e 11 Circuit Design, Inc. Method of serial data input to the PLL OPERATION GUIDE
. After the RF channel table plan is decided, the data needs to be allocated to the ROM table and read from there or calculated with the software. Together with this setting data, operation bits that decide operation of the PLL must be sent to the PLL. The operation bits for setting the PLL are as follows. These values are placed at the head of the reference counter value and are sent to the PLL. 1. 2. 3. CS: Charge pump current select bit CS = 0

CLK [Clock]: Data is shifted into the shift register on the rising edge of this clock. 2. LE [Load Enable]: Data in the 19-bit shift register is transferred to respective latches on the rising edge of the clock. The data is transferred to a latch according to the control bit CNT value. 3. Data [Serial Data]: You can perform either reference counter setup or programmable counter setup first. OG_LMD-400-R-C_v12e 12 Circuit Design, Inc. OPERATION GUIDE
. TIMING CHART Control timing in a typical application is shown in Figure 3. Initial setting of the port connected to the radio module is performed when power is supplied by the CPU and reset is completed. MOS-FET for supply voltage control of the radio module, RXSEL and TXSEL are set to inactive to avoid unwanted emissions. The power supply of the radio module is then turned on. When the radio module is turned on, the PLL internal resistor is not yet set and the peripheral VCO circuit is unstable. Therefore data transmission and reception is possible 40 ms after the setting data is sent to the PLL at the first change of channel, however from the second change of channel, the circuit stabilizes within 20 ms and is able to handle the data. Changing channels must be carried out in the receive mode. If switching is performed in transmission mode, unwanted emission occurs. If the module is switched to the receive mode when operating in the same channel, (a new PLL setting is not necessary) it can receive data within 5 ms of switching*1. For data transmission, if the RF channel to be used for transmission is set while still in receiving mode, data can be sent at 5 ms after the radio module is switched from reception to transmission*2. Check that the Lock Detect signal is high 20 ms after the channel is changed. In some cases the Lock Detect signal becomes unstable before the lock is correctly detected, so it is necessary to note if processing of the signal is interrupted. It is recommended to observe the actual waveform before writing the process program.
*1 DC offset may occur due to frequency drift caused by ambient temperature change. Under conditions below -10 C, 10 to 20 ms delay of DO output is estimated. The customer is urged to verify operation at low temperature and optimize the timing.
*2 Sending 10101.. preamble just after switching to transmission mode enables smoother operation of the binarization circuit of the receiver. Preamble length:
