Description
Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

serial
The U4289BM is controlled via the 2-wire bus. One module address byte, two subad-
dress bytes and five data bytes enable programming.
The module address contains a programmable address bit A 1, which (along with
address select input AS, pin 4), enables the operation of two U4289BM devices in one
system. If bit A 1 is identical with the status of the address select input AS, the chip is
selected.
The subaddress determines which of the data bytes is transmitted first. If the subad-
dress of the R-divider is transmitted, the sequence of the next data bytes is DB 0
(Status), DB 1 and DB 2. If the subaddress of the N-divider is transmitted, the sequence
of the next data bytes is DB 3 and DB 4. The bit organization of the module address,
subaddress and 5 data bytes is shown in table “Bit Organization” on page 7.
Each transmission on the bus begins with the “START” condition and has to be ended
by the “STOP” condition (see table “Transmission Protocol” on page 7).
The integrated circuit U4289BM has two separate inputs for the AM and FM oscillators.
Pre-amplified AM and FM signals are fed to the 16-bit R-divider via the AM/FM switch.
The AM/FM switch is software controlled. Tuning steps can be selected by the 16-bit
R-divider.
Furthermore, the device provides a digital memory phase detector and two separate
current sources for AM and FM amplifier (charge pump) as given in the Table “Electrical
Characteristics” on page 4. It allows independent gain adjustment, providing high cur-
rent for high-speed tuning and low current for stable tuning.
