FUNCTIONAL DESCRIPTION
The TSA6060 contains the following parts:
Separate input amplifiers for the AM and FM VCO
signals.
A 17-bit programmable counter.
A digital memory phase detector.
A reference frequency channel which contains a 4 MHz
or 8 MHz crystal oscillator which is followed by a
reference counter. The reference frequency can be
either 1, 5, 10 or 50 kHz and is applied to the digital
memory phase detector. The reference counter can also
output a 40 kHz reference frequency to pin 9 for
communication between the FM/IF system and the
microcontroller-based tuning interface IC (TEA6100).
A programmable current amplifier (charge pump) which
consists of a 25 mA and a 500 mA current source. This
allows adjustment of the loop gain thereby providing
high-current high-speed tuning and low-current stable
tuning.
A one-input-two-output tuning voltage amplifier. One
output is connected to the external AM loop filter and the
other output to the external FM loop filter. Under
software control, the AM output is switched to a low
impedance to ground by the FM/AM switch in the FM
position. The FM output is switched to a low impedance
to ground by the AM/FM switch in the AM position. The
outputs can deliver a tuning voltage of up to 10.5 V.
An I2C-bus interface with data latches and control logic.
The I2C-bus is intended for communication between
microcontrollers and different ICs or modules. Detailed
information concerning the I2C-bus specification is
available on request.
A software controlled band switch output.
Controls
The TSA6060 is controlled via the 2-wire I2C-bus.
For programming there is one module address, a logic 0
(R/W bit) and four data bytes. The module address
contains an address select bit (AS) which enables two
TSA6060s to be operated in one system.
The auto-increment facility of the I2C-bus allows
programming of the TSA6060 within one transmission
(address + 4 data bytes).
The TSA6060 can also be partially programmed.
Transmission must then be ended by a STOP condition.
