TRF1400 General Description
The TRF1400 VHF/UHF RZ ASK remote control receiver is specifically designed for RZ ASK (return-to-zero amplitude-shift keyed) commu- nications systems operating in the 200-MHz to 450-MHz band. This device is targeted for use in automotive and home security systems, garage door openers, remote utility metering, and other low-power remote control and telemetry systems.
A complete RZ ASK receiver solution on a chip, the TRF1400 requires only a minimum of external components for operation. This significantly reduces the complexity and footprint of new Ndesigns compared with current discrete receiver designs. The TRF1400 requires no manual alignment when using external SAW (surface acoustic wave) filters. For a lower-cost solution, the device is also compatible with external LC components.
The TRF1400 also includes several on-chip features that normally require additional circuitry in a receiver system design. These include two low-noise front-end amplifiers, an RF amplifier/comparator for detection and shaping of input signals, and a demodulated RZ ASK baseband TTL-level output that readily interfaces to self-synchronizing devices. Also included is on-chip Manchester decoding logic that provides a specially formatted TTL data output, synchronized with a trigger output, for easy interface to any microcontroller using Manchester-encoded data.

TRF2020 General Description
The Texas Instruments (TI) TRF2020 is an integrated high performance frequency synthe- sizer device. The TRF2020 consists of one main 1.2-GHz synthesizer and two auxiliary 250-MHz synthesizers. Each synthesizer has an independent dual-modulus prescaler and separate powerdown modes.These features provide maximum flexibility for the design of 900-MHz wireless systems.
The main synthesizer consists of a 32/33-modulus prescaler with an 11-bit counter, a phase-frequency detector, and a charge pump. The phase-frequency detector is referenced to an internal reference frequency that is derived from an external TCXO signal. The phase-frequency detector is also provided with a dead-zone compensation circuit that reduces synthesizer phase noise during locked conditions.
Each auxiliary synthesizer consists of an independent 8/9-modulus prescaler with an 11-bit counter, a phase-frequency detector, and a charge pump. Similar to the main synthesizer, each auxiliary synthesizer's phase-frequency detector is referenced to an internal reference frequency that is derived from an external TCXO signal.
The external TCXO signal is prescaled by an 11-bit counter and then distributed to three independent postscalers. Each postscaler provides a selectable, divide-by-1, -2, -4, or -8 function before the reference signal is distributed to the associated synthesizer phase detector. The reference frequency prescaler and independent postscalers are software programmable.
To achieve minimum lock-up time, each synthesizer contains a speed-up mode charge pump capable of providing 2 mA output current and an analog switch that can change the loop-filter time constant. The duration of the speed-up mode operations can be independently controlled with software.
The states of the three internal lock detectors are provided on a programmable, combinational logic output; each synthesizer can be selected independently or ANDed together.
The device is programmed over a three-wire, synchronous, serial data bus (clock, data, strobe) with achievable bit rates as high as 20 Mbits/sec. The data is partitioned into words in such a manner that static parameters may be sent once during initialization, and dynamic parameters, such as frequency, may be sent as often as needed. The TRF2020 is offered in a 24-pin plastic thin-shrink small-outline package (TSSOP) and is characterized for free-air operation from 40°C to 85°C.
