7.0 SYSTEM TIMING
All system timing functions, including the 11.5625 MHz display pixel clock, are produced in the
digital PLL & TV sync timing block using the oscillator output from the Texas Instruments CF72306
or CF72416 data slicer. The display sync signals generated are flexible and can be software
controlled to provide interlaced or non-interlaced text displays with locked of unlocked field sync.
The Eurotext chip uses a digital PLL which can lock onto a VCR playback video signal, allowing
EUROTEXT to be used for OSD during VCR playback.
8.0 I

C INTERFACE
The EUROTEXT device acts as a slave transceiver and follows I
2
C-bus protocols.
Data Transfer to EUROTEXT
The sending of command and data bytes to the EUROTEXT is initiated by the bus master which
places a start condition on the bus followed by the bus address with the R/W bit set to 0 (hex 22).
Command and data bytes are then transferred to the EUROTEXT which acts as a slave receiver. The
transfer can consist of any number of bytes and the transfer is terminated when the bus master places
a ‘start’ or ‘stop’ condition on the bus.
