GENERAL DESCRIPTION
The TDA8735 is a single-chip PLL synthesizer designed
for satellite receivers. The device can be set to two
different addresses which can be used in applications
where independently tuned VCOs are required.
To adapt to different frequency accuracy, 3 reference
frequencies are selectable via the I2C-bus. The charge
pump current can be set to 2 values with a ratio of 1 : 100
via the I2C-bus.
A programmable switch (open-collector) is integrated to
enable mode or normal switching, or other types of
application.
