U3550BM Low-Power FM Transmitter / Synthesizer System 26 to 50 MHz Description The receive part is designed for a double-conversion architecture. The incoming radio-frequency signal will be filtered and amplified before reaching the first mixer. At this stage, the RF signal will be converted down to the first intermediate frequency (10.7 MHz) by using a local adjustable oscillator (VCO3). The frequency of this oscillator is controlled by the PLL. The transmitter part contains two PLL-controlled VCOs. The frequency modulation is accomplished by superposing the incoming audio signal on the first PLL control voltage. In this system, the frequency is a product of mixing VCO1 with local oscillator (VCO3). The FMmodulated carrier is amplified by external power amplifier before entering the output filter and the antenna connector. Gm bH The U3550BM is a radio-frequency IC for analog cordless telephone applications in the 26/50-MHz band (CTO standard). The IC performs full duplex communication. The transmitting and receiving frequency depends on whether the IC is used in the handset or in the base station. nt s The U3550BM’s frequency converter consists of an FM transmitter with switchable output power and receiver Mixer 1 in the same unit. A two-wire bus interface can be used for frequency control as well as for switching the transmitter’s power amplifier and the receiver. Fine frequency adjustment of the reference crystal oscillator is programmable.

A2, 10-Sep-98 Preliminary Information U3550BM VCO Adjustments Duration Adjustment of the Anti-Backlash Signals To be able to use a wide VCO frequency range (i.e., VCO2 = 26.3 to 49.9 MHz), VCO1 and VCO2 have a rough adjust and a fine adjust to increase the frequency range given by the phase comparator. Gm bH The phase comparators of the modulator- and the mixerloop have a 2-bit adjustment for the duration of the upand down pulses when the loop is locked (anti-backlash). The 4 rough adjusts for VCO1 and VCO2 (3 used in VCO1) are correlated to the country setting. For each country, there are two sets of VCO rough adjust settings, one for the base and one for the handset (see tables Channel Frequencies, Dividers and Country Settings). Best results can be achieved by setting all the bits (AMOD[2:1], AMIX[2:1]) to 0. Adjustment of the Modulator Gain To achieve the adaption to the various country standards, there is a fine adjust with 32 steps for VCO1 and VCO2. These fine adjusts can be set manually (for test purposes) or by the automatically mode. Theoretically, the indicator of the change (increase/ decrease when the voltage of the phase comparator is too high) is selectable. The programming value ‘1’, however, is necessary. To fulfill all requirements of the various countries, three conversion gains of the modulator are selectable by the bits GMOD[1:0]. nt s For country settings, see tables Channel Frequencies, Dividers and Country Settings. For the ranges, see tabel Electrical Characteristics (RF transmitter). Setting normal conditions VCO1: EAFA1 = 1, automatic fine adjust VCO1 enabled SAFA1 = 1, sign of auto fine adjustment VCO1 = 1. om po ne Clock-Output Divider Adjustment Setting for VCO2 is identical. For VCO3, there is no internal adjustment. The MCKO pin is a clock output derived from the crystal oscillator. It can be used to drive a microprocessor or other remote components and thereby reduces the number of crystals required. Speed-up of the Modulator Loop Filter To obtain a fast locking time for the modulator loop, there is a precharge and a speed-up mode for the external loop filter. The crystal oscillator frequency can be divided by an integer value: 1, 2, 3, 4, 6 or switched off. During receive mode (VCO3 enabled, VCO1 disabled), the modulator loop filter is precharged to 1.25 V. The divider value is adjusted by an analog level on the MCKA pin. Ad ro nic C During the first 30 ms after enabling VCO1, the modulator phase comparator is in speed-up mode. In this mode, the current of the phase comparator which charges the loop filter is much larger than in normal mode. The duration of the speed-up mode depends on the number of oscillator clock cycles. Table 1 shows the clock-output value on MCKO for different divider values and the corresponding level required on MCKA. Crystal oscillator = 11.15 MHz. Table 1.

After 223 cycles, the correct division is executed.

A2, 10-Sep-98 Preliminary Information U3550BM Ozone Depleting Substances Policy Statement It is the policy of TEMIC TELEFUNKEN microelectronic GmbH to Gm bH 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). nt s 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 TELEFUNKEN microelectronic GmbH semiconductor division has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. om po ne 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. Ad ro nic C TEMIC 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.
