6.0 TRC103 Design-in Steps
Designing a TRC103 into an application consists of seven steps:
1. Select the frequency band for operation: 863-870, 902-928 or 950-960 MHz. This allows the frequency-
specific hardware components for the TRC103 to be determined. These include the SAW filter and its
matching components and the VCO tank inductors.
2. Select the modulation type, FSK or OOK, and the RF data bit rate. This allows the configuration of the
TRC103 on-chip filters, the data and clock recovery circuitry and related parameters to be determined.
3. Select the radio regulation under which to operate. This allows the transmitter power level to be deter-
mined.
4. Select the frequency channel or channels to be used. This allows the configuration values for the fre-
quency synthesizer to be tabulated.
5. Select the operating mode to be used: continuous, buffered or packet. For continuous mode, determine if
the TRC103 internal data and clock recovery feature will be used. This allows the configuration of a num-
ber of mode-related registers in the TRC103 to be determined. For packet or buffered mode, select the
data encoding, preamble length, start pattern, FIFO length and the mapping of the TRC103 host proces-
sor interrupts. For packet mode, select packet filtering options (address, CRC, etc.). From these deci-
sions, values for the related configuration registers in the TRC103 can be determined.
6. If needed, prepare a battery power management strategy and determine when various system radios may
be configured for low power consumption.
7. Based on the selections and determinations above, compile the configuration data to be stored in the host
microcontroller to support TRC103 operation.
The details of each of these steps are discussed below.
6.1 Determining Frequency Specific Hardware Component Values
6.1.1 SAW Filters and Related Component Values
RFM offers a low-loss SAW RF filter for each of the TRC103’s operating bands. The part numbers for these SAW
filters and the values of the related tuning components are given in Table 53 (see Figure 2 for component loca-
tion). The SAW filters are designed to take advantage of the TRC103’s differential output to achieve low insertion
loss and high out-of-band rejection.

6.1.2 Voltage Controlled Oscillator Component Values
The TRC103 VCO requires four external components for operation, two tank circuit inductors and two power sup-
ply decoupling capacitors. It is important to use high-Q chip inductors in the tank circuit. This assures low phase
noise VCO operation and minimum interference from signals near the TRC103’s operating frequency due to
