... Codecs used in PCM systems. They contain the band-limiting filters and the analog to digital conversion circuits that conform to the desired transfer characteristic. The MV3506 and MV3508 provide the European A-Law companding and the MV3507 provides the North American -Law companding characteristic ...

... Figure 2: Functional block diagram (pin numbers for the MV3507A are in brackets) 2 more than 15 consecutive zeros. An additional feature of the MV3506 special circuit to eliminate any transmitted idle channel noise during quiet periods. When the input of these chips is-such that for 250ms the only code words generated were +0, - -1, the output word will ...

... The basic timing is provided by the system clock which is divided down internally to provide the various filter clocks and the timing for the conversions. The transmit and receive strobes and clocks must be locked to this clock so that the PCM data matches the sample rates. MV3506/7/8 3 ...

... Test/Squelch Enable (Intemal Connection/Digital Input). This pin is an internal test connection on the MV3506, MV3507 and it is the squelch enable input on the MV3508. On the MV3506/7 it should be left unconnected or connected to the A GND pin via a capacitor for normal operation. On the MV3508 it should be tied high to enable the squelch feature and it should be left unconnected otherwise ...

... FLT OUT pin can be connected to OUT- to realise a low output impedance with unity, increased or reduced gain. This allows easy calibration of the receive channel. The V pin has the capability of driving 0dBm into a 600 load (see OUT Fig.4) . Positive Supply (Power Input). 5V. MV3506/7/8 for coder auto zero operation. The AZ pin. These IN 5 ...
