TP3040, TP3040A PCM Monolithic Filter  
General Description  
Features  
Y
Designed for D3/D4 and CCITT applications  
b
The TP3040/TP3040A filter is a monolithic circuit contain-  
ing both transmit and receive filters specifically designed for  
PCM CODEC filtering applications in 8 kHz sampled sys-  
tems.  
Y
Y
a
Low power consumption:  
5V, 5V power supplies  
45 mW (0 dBm0 into 600X)  
30 mW (power amps disabled)  
Power down mode: 0.5 mW  
20 dB gain adjust range  
The filter is manufactured using microCMOS technology  
and switched capacitor integrators are used to simulate  
classical LC ladder filters which exhibit low component sen-  
sitivity.

No external anti-aliasing components  
Sin x/x correction in receive filter  
50/60 Hz rejection in transmit filter  
TTL and CMOS compatible logic  
All inputs protected against static discharge due to  
handling  
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 pro-  
vides a flat response in the passband and rejection of sig-  
nals below 200 Hz and above 3.4 kHz.  
RECEIVE FILTER STAGE  
The receive filter is a fifth order elliptic low pass filter de-  
signed to reconstruct the voice signal from the decoded/de-  
multiplexed signal which, as a result of the sampling pro-  
cess, is a stair-step signal having the inherent sin x/x fre-  
quency response. The receive filter approximates the func-  
tion required to compensate for the degraded frequency re-  
sponse and restore the flat passband response.
