Product Overview
TRC101 is a highly integrated single chip, zero-IF, multi-channel, low
power RF transceiver. It is an ideal fit for low cost, high volume, two way
short-range wireless applications for use in the unlicensed 300-1000 MHz
frequency bands. All critical RF and baseband functions are completely
integrated in the chip, thus minimizing external component count and
simplifying and speeding design-ins. Use of a low cost, generic 10MHz
crystal and a low-cost microcontroller is all that is needed to create a
complete link. The TRC101 also incorporates different sleep modes to
reduce overall current consumption and extend battery life. Its small size
with low power consumption makes it ideal for various short range radio
applications.

... L3 Antenna Design Considerations The TRC101 is designed to drive a differential output such as a Dipole antenna or a Loop. The loop antenna is ideally suited for applications where compact size is required. The dipole is typically not an attractive option for compact designs due to its inherent size at resonance and distance needed away from a ground plane efficient antenna ...

... Achieving higher data rates • Crystal Oscillator The TRC101 incorporates an internal crystal oscillator circuit that provides a 10MHz reference, as well as internal load capacitors. This significantly reduces the component count required. The internal load capacitance is programmable from 8.5pF to 16pF in 0.5pF steps. This has the advantage of accepting a wide range of crystals from many different manufacturers having different load capacitance requirements ...

... The DQD is a unique function of the TRC101. The DQD circuit looks at the prefiltered incoming data and counts the “spikes” of noise for a predetermined period of time to get an idea of the quality of the link. This parameter is programmable through the Data Filter Command Register. The DQD count threshold is programmable from counts ...

... RSSI output. Typically, Automatic Gain Control (AGC) is used to reduce the input signal level upon saturation of the RSSI in the presence of strong or near-field ASK signals. The TRC101 does not have an AGC option, however, the input LNA gain is programmable. The output RSSI signal level may be sampled upon enabling of the receiver to test if the signal level is in saturation ...

... The TRC101 is equipped with a standard SPI bus that is compatible to almost all SPI devices. All functions and status of the chip are accessible through the SPI bus. Typical SPI devices are configured for byte write operations. The TRC101 uses word writes so the nCS pin(3) should be pulled low for 16 bits. ...

... AFA has to be disabled during the read by clearing the "AFEN" bit in the AFA Register (bit 0). To read the status register, initiate a command beginning with a ‘0’ and read the remaining bits on the SDO line. All other commands begin with a ‘1’ so the TRC101 recognizes a command vs. status.
