CT2-RX/TX IC
Description
The IC for digital cordless telephone application is fabricated using TEMIC's most advanced UHF process. It covers the CT2 band (864 MHz to 868 MHz) as well as the CT2 Plus band (up to 952 MHz). The RX/TX circuit provides the down conversion to the data stream and the up conversion from the first IF. In conjunction with TEMIC's RF front end, Twin PLL, I/Q modulator and AMDs CT2 PhoXTM controller AM 79C4xx a complete CT2 IC kit is available. Electrostatic sensitive device. Observe precautions for handling.
Features
D Low supply voltage 2.9 V typical (min. 2.7 V) D Provides down conversion to the data stream, D D D D D D D
up conversion from the first IF Integrated UHF and VHF VCOs Low noise figure of RX path (NF 10 dB) RX and TX power down First IF filter used for transmit as well receive mode Temperature compensated logarithmic Receiver Signal Strength Indicator (RSSI) with a 75 dB dynamic range Low power consumption in RX and TX mode (<20 mA typ.) SSO28 plastic package
Benefits
D Low power consumption results in extended talk time D Few external components and very small package

Functional Description
MX1
Mixer 1 converts the RF signal to the first IF. It has a high impedance, unsymmetrical input and a symmetrical open collector output.
COMP
The comparator circuit with 100 kW input resistor and external input biasing has a 10 mV hysteresis. It is designed to square up the demodulated data signal.
MX2
The second mixer provides the down conversion to the second IF. An external SAW filter is placed at its input to provide rejection of the image frequency and spurious signals that went through the RF filtering.
MX3
The third mixer converts the 800 kHz signal coming from the modulator circuit to the IF frequency. It has a high impedance, unsymmetrical input and a symmetrical open collector output.
MX4
This mixer is designed for the up conversion of the RF frequency. It has a high impedance, unsymmetrical input and a symmetrical open collector output. The image rejection is obtained by external RF filtering. The same first IF filter is used for the transmit path and the receive path. In the transmit path, this filter is supposed to eliminate the mixing products from MX3, in particular, the harmonics of the IF frequency.
LIMITER / RSSI
This block contains a high gain (100 dB) amplifier, providing a limited signal at the second IF frequency for the demodulation, as well as a signal strength indicator providing an output voltage proportional to the input power.
Demod
The quadrature demodulator in the receiving path contains an internal 10 pF quadrature capacitor to couple the IF signal to the external Tank providing the 90 degree phase shift. An external bit slicer reshapes the bits, a sample and hold circuit maintains the average DC value at the demodulator when switching the signal between transmission and reception.
VCO1
The UHF VCO covers the frequency band up to 700 MHz. For external VCO application this circuit can be used as a buffer stage.
VCO2
This VCO covers a frequency band up to 400 MHz.

Ozone Depleting Substances Policy Statement
It is the policy of TEMIC Semiconductor GmbH to 1. Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances ( ODSs). The Montreal Protocol ( 1987) and its London Amendments ( 1990) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. TEMIC Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2 . Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency ( EPA) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C ( transitional substances ) respectively. TEMIC Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances.
We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use TEMIC products for any unintended or unauthorized application, the buyer shall indemnify TEMIC against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
