Introduction

The MSP 3410 B is a single-chip Multistandard Sound Processor for applications in analog and digital TV sets, satellite receivers and video recorders.

The MSP-family, which goes back to the MSP 2400, demonstrates in an impressive way the progressive development towards highly integrated ICs, offering more and more features and flexibility. The development of the MSP 2410 included an automatic gain control but reduced the amount of external components. The MSP 2410 reached a high level of performance and is the basis for the new generation.

The MSP 3410 B facilitates profitable multistandard capability, offering the following advantages:

– two selectable analog inputs (TV- and SAT-IF sources)

– Automatic Gain Control (AGC) for analog input: input range: 0.14 – 3 Vpp

– integrated A/D converter for sound-IF inputs

– all demodulation and filtering is performed on chip and is individually programmable

– simple realization of both digital NICAM standards (UK/Scandinavia)

– no external filter hardware is required

– only one crystal clock (18.432 MHz) is necessary

– Pay-TV for NICAM-mode

– FM carrier level calculation for automatic search algorithms and carrier mute function

– high deviation FM-mono mode (max. deviation: approx. ±360 kHz)
