1.3 GHz universal bus-controlled

TV synthesizer

TSA5520; TSA5521

Fig.4 Normal mode; 19-bit data format (RSA = 0).

For TSA5520 bit RSB = 1 at power-on; the reference divider is 512 or 1024.

For TSA5521 bit RSB = 0 at power-on; the reference divider is 640.

For TSA5520/TSA5521 the value of RSB can also be programmed by using the 27-bit data format. When returning to the normal mode, bit RSB remains

as programmed with the 27-bit data word.

Fig.5 Test and features mode; 27-bit data format.

For TSA5520 bit RSB = 1 at power-on; the reference divider is 512 or 1024.

For TSA5521 bit RSB = 0 at power-on; the reference divider is 640.

For TSA5520/TSA5521 the value of RSB can also be programmed by using the 27-bit data format. When returning to the normal mode, bit RSB remains

as programmed with the 27-bit data word.
