The MT1503EDC is a tuner module for reception in VHF Band III and L-Band compliant to the DAB EUREKA 147 standard. It performs a down-conversion to an intermediate frequency followed by further signal processing based on an integrated baseband processor. A serial bus interface serves as a digital audio output.

FEATURES

• Double down-conversion for L-Band, Single down-conversion for VHF Band III reception

• 50 Ω antenna input matching

• External RF AGC (pin diode)

• Gain controlled LNAs for both bands

• Selectable RF AGC threshold level

• Tunable preselection filter for better image rejection

• IF SAW filter

• Selectable IF AGC threshold

• Decoding of full DAB audio/data stream according to EUREKA 147 standard

• Decoding of FIC/FIDC and PAD data

• Processing of data services in parallel to audio service

• Supports stream and packet mode

• Error concealment and dropout masking

• Extended data processing capabilities

• Very small form factor

• Shielded metal housing

• USART bus for control functions

• RDI and SPI interfaces for external DMB and data decoders

• USB and SSO interface optional

• Extended parametric temperature range of -40° to +85°C

• 12 V phantom power feeding for an active antenna

• On-board flash memory

• Lead free and RoHS compliant

• Qualified according to automotive requirements

APPLICATIONS
