Description : MSP34x5G Multistandard Sound Processor Family

[Micronas]

Introduction
The MSP 34x5G family of Single-chip Multistandard Sound Processors covers the sound processing of all analog TV standards worldwide, as well as the NICAM digital sound standards. The full TV sound processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed in a single chip. Figure 1–1 shows a simplified functional block diagram of the MSP 34x5G.
These TV sound processing ICs include versions for processing the multichannel television sound (MTS) signal conforming to the standard recommended by the broadcast Television Systems Committee (BTSC). The DBX noise reduction, or alternatively, Micronas Noise Reduction (MNR) is performed alignment free.
Other processed standards are the Japanese FM-FM multiplex standard (EIA-J) and the FM-Stereo-Radio standard.
Current ICs have to perform adjustment procedures in order to achieve good stereo separation for BTSC and EIA-J. The MSP 34x5G has optimum stereo performance without any adjustments.

NTE Electronics
Description : Intergrated Circuit FM stereo Transmitter

Description:

The NTE7200 is a monolithic intergrated circuit in an 18-Lead DIP type package designed for use as a stereo transmitter. This device consists of a stereo modulator that creates stereo composite signals, an FM modulator that creates FM signals, and an RF amplifier. The stereo modulator develops composite signals made up of a MAIN (L+R) signal, a SUB (L-R) signal and a pilot (19kHz) signal using 38kHz crystal oscillators.

The FM modulator has carriers on the FM broadcast band (75 to 108MHz). The RF amplifier transmits the stereo encoded FM signals and is also a buffer for the FM modulator. The stereo transmitter is equipped with a constant voltage pin for a variable capacitor that is used to finly adjust the FM frequency.



Features:

• Low Operating Voltage Range (1.0V to 2.0V)
