������)XQFWLRQ
The TDA6060XS RF TV modulator is a single silicon chip, controlled by software, that translates
video and audio signals to any worldwide television RFchannel format. This IC is suitable for all
modulator boxes including satellite receivers, cable headend, set-top boxes, video recorders and
games.
������)HDWXUH�’HVFULSWLRQ
The TDA6060XS IC combines a digitally programmable phase locked loop (PLL) with a
multi-standard video modulator and programmable sound FM and AM modulator. This
highly integrated chip allows for simpler design and lower system cost and compatibility with
all world standards, including PAL, NTSC and SECAM. It offers designers maximum
flexibility with an on-board PLL that permits the tuning process, gain settings and status
with I2C bus microprocessor control. The frequency of the modulator oscillator
can be set precisely from 30 MHz to 950 MHz in increments of 250 kHz. The frequency
range VHF Low, VHF High, Hyper band and UHF can be changed with different tank circuit
applications.
The modulator block (shown in Figure 1) includes:a digitally programmable I2C bus controlled phase locked loop (PLL) controlled

The TDA6060XS gives the designer maximum flexibility by allowing many programmable features
and precision settings such as Picture/Sound carrier, video gain, video modulation depth, video
clipping flag and audio gain. The programmable features and settings/readings are shown in
Table 1.
