tda5225 Infineon Technologies Corporation, tda5225 Datasheet - Page 23

• Manufacturer Part Number: tda5225
• Description: Enhanced Sensitivity Multi-channel Quad-conf Igurat Ion Receiver With Digital Slicer
• Manufacturer: Infineon Technologies Corporation

The resulting CLK_OUT frequency can be calculated by:
Figure 8
The maximum CLK_OUT frequency is limited by the driver capability of the PPx pin and
depends on the external load connected to this pin. Please be aware that large loads
and/or high clock frequencies at this pin may interfere with the receiver and reduce
performance.
After Reset the PPx pin is activated and the division factor is initialized to 11 (equals
f
A clock output frequency higher than 1 MHz is not supported.
For high sensitivity applications, the use of the external clock generation unit is not
recommended.
