Multiband Analog and
Digital Television Tuner
General Description
The MAX3543 hybrid broadband single-conversion tele-
vision tuner is designed for use in analog (PAL, SECAM)
+ digital (DVB-T, GB20600) television sets and terrestrial
receivers. It receives all television bands from 47MHz
to 862MHz and converts the selected channel to an
industry-standard 36MHz IF.
The MAX3543 includes a variable-gain low-noise input
amplifier; an RF tracking filter; an image rejection mixer;
a peak detector; an optional internal, self-contained
RF gain-control loop (RFAGC); a VCO with fractional-N
PLL; an IF bandpass filter; an IF variable-gain amplifier;
separate analog and digital IF outputs; and a crystal
oscillator.
The MAX3543 is available in a small, 6mm x 6mm, thin QFN
package, and the application circuit fits in 20mm x 25mm on
a two-layer board with single-sided component mounting.

FUNCTION
VCO[1:0]
7:6
VCO select. Selects one of three VCOs when VAS = 0, or selects the VCO starting
band when VASS = 0.
01
00 = Selects VCO1 (approximately 2200MHz to 2800MHz)
01 = Selects VCO2 (approximately 2800MHz to 3500MHz)
10 = Selects VCO3 (approximately 3500MHz to 4400MHz)
11 = VCO shutdown
VSUB[3:0]
5:2
0011
VCO sub-band select. Selects one of 16 possible VCO sub-bands when VAS = 0,
or selects the VCO starting sub-band when VASS = 0.
0000 = Selects SB0
…
1111 = Selects SB15
VDIV[1:0]
1:0
VCO divider ratio select.
00 = Sets VCO divider to 4 (use when fLO > 550MHz)
00 01 = Sets VCO divider to 8 (use when 275MHz < fLO < 550MHz)
10 = Sets VCO divider to 16 (use when 137.5MHz < fLO < 275MHz)
11 = Sets VCO divider to 32 (use when fLO < 137.5MHz)
