Product data sheet
7.1 General
Table 2:
TDA6500TT and TDA6501TT are programmable 2-mixer, 3-oscillator and synthesizer
MOPLLs intended for pure 3-band tuner concepts.
The device includes two double balanced mixers for the low and mid/high bands and three
oscillators for the low, mid and high bands respectively. The band limits for PAL tuners are
shown in
Table 3:
Other functions are an IF amplifier, a wide-band AGC detector and a PLL synthesizer.
Two pins are available between the mixer output and the IF amplifier input to enable
IF filtering for improved signal handling.
Bit P0 enables Port P0 and the low band mixer and oscillator (see
Port P1, the mid/high band mixer and the mid band oscillator. Bit P2 enables Port P2 and
bit P3 enables Port P3. When Ports P0 and P1 are disabled, the mid/high band mixer and
the high band oscillator are enabled.
