TP3040 Datasheet Pcm Monolithic Filter

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: TP3040 TP3040A PCM Monolithic Filter September 1994 TP3040 TP3040A PCM Monolithic.

General Description

The TP3040 TP3040A filter is a monolithic circuit containing both transmit and receive filters specifically designed for PCM CODEC filtering applications in 8 kHz sampled systems The filter is manufactured using microCMOS technology and switched capacitor integrators are used to simulate classical LC ladder filters which exhibit low ponent sensitivity TRANSMIT FILTER STAGE The transmit filter is a fifth order elliptic low pass filter in series with a fourth order Chebyshev high pass filter It provides a flat response in the passband and rejection of signals below 200 Hz and above 3 4 kHz RECEIVE FILTER STAGE The receive filter is a fifth order elliptic low pass filter designed to reconstruct the voice signal from the decoded demultiplexed signal which as a result of the sampling process is a stair-step signal having the inherent sin x x frequency response The receive filter approximates the function required to pensate for the degraded frequency response and restore the flat passband response
