MT3511

RF MicroDigitizer™ for Software Defined Radio

The MT3511 is a single-chip RF-to-Digital Converter (RDC) that integrates

the functions of a high-end AM/FM silicon tuner with an analog-to-digital

converter targeted for automotive software defined radio platforms.

Description

The MT3511 is a RF-to-digital converter specifically designed for automotive infotainment systems. The

integrated 16-bit analog to digital converter (ADC) digitizes the IF signal and provides a suitable

interface for high-end software defined radio architectures. A generic processor (e.g. DSP) can be used

to demodulate the supported radio standards.

The MT3511 features integrated RF LNAs as well as RF AGCs for AM and FM in order to ensure

excellent sensitivity as well as state-of-the-art strong signal performance. The RF attenuation range can

optionally be extended by adding external PIN diodes.

The integrated image reject mixer converts the RF signal to an intermediate frequency (IF) while the

desired channel is isolated using an external ceramic filter. After adjusting the gain with the IF amplifier

the analog IF signal is digitized using the on-chip 16-bit ADC, which provides a serial data output for

software-demodulation on an external processor.

This serial data output does not only contain radio signal information but also provides tuner status

information in order to optimize the external signal processing. The MT3511 additionally integrates a

state machine for frequency tuning actions enabling inaudible checks of alternative frequencies (AF).

Due to its high level of integration, the MT3511requires a minimum of external components. Complying

with automotive requirements the MT3511 supports an extended temperature range of

-40° to +85°C and is specifically designed for qualification according to the AEC-Q100 standard.
