Satellite demodulator and decoder

TDA8044

QUICK REFERENCE DATA

Notes

1. Programmable internal frequencies possible:

a) Values 10.7, 16, 32 or 64 MHz for CFS = 0.

b) Values 16, 24, 48 or 96 MHz for CFS = 1.

2. CFS is set to logic 0.

3. Without switching internal clock frequencies, a range of 1 decade can be covered. To cover the full range of symbol

frequencies, internal clock frequencies and external (SAW) filters must be switched. Details can be found in the

application note.

and a clock frequency of 64 MHz.

5. Implementation loss at the demodulator output and minimum S/N to lock the TDA8044 are measured including tuner

in a laboratory environment at a symbol rate of 27.5 Msymbols/s and a clock frequency of 64 MHz.
