M I C R O T U N E ®

The MT7402 Hybrid Car TV Tuner

Module is specifically designed to meet

the demanding performance targets of

automotive customers, at an attractive

price. This tuner is compatible with both

analog TV standards as well as with the

digital DVB-T standard, enabling

customers to realize a highly integrated,

high-performance, cost-effective hybrid

car TV receiver solution. The MT7402

Tuner Module converts the RF signal into

an IF signal. It combines a low noise

figure with high gain and offers an

operational frequency of 45 MHz to

860 MHz divided into VHF low, VHF high

and UHF bands. Signal paths for the

three different bands are realized

separately, providing excellent

performance. The RF AGC can be

controlled either externally via the RF

AGC voltage input or automatically via

the internal AGC loop control, with

programmable parameters for threshold

and time constant. The address select

function enables the use of up to four

MT7402 tuners to realize high

performance functions like tuner

diversity, frequency diversity, or blending

between analog TV and DVB-T

reception.

The analog TV section provides a

balanced IF output capable of directly

driving an external surface acoustical

wave (SAW) filter. The external

demodulation can cover all analog TV

standards, provided that the picture

carrier is fixed at 38.9 MHz and the

filtering of the tone carrier is done

accordingly.

The digital TV section contains a

switchable (7/8 MHz) SAW filter for

excellent adjacent channel performance,

an IF amplifier for filter loss

compensation, and offers a balanced IF

output to directly drive an external DVB-T

demodulator. The IF gain can be

controlled externally via the IF AGC

voltage input.

Band selection, tuning, and

several tuner functions are controlled via

Module combines very small size with

high performance in harsh environments,

making them especially suitable for

automotive and mobile applications.
