COMBO® II Programmable PCM CODEC/Filter  
General Description  
Features  
n Complete CODEC and FILTER system including:  
— Transmit and receive PCM channel filters  
— µ-law or A-law companding encoder and decoder  
— Receive power amplifier drives 300Ω  
— 4.096 MHz serial PCM data (max)  
n Programmable Functions:  
The TP3070 and TP3071 are second-generation combined  
PCM CODEC and Filter devices optimized for digital switch-  
ing applications on subscriber line and trunk cards. Using  
advanced switched capacitor techniques, COMBO II com-  
bines transmit bandpass and receive lowpass channel filters  
with a companding PCM encoder and decoder. The devices  
are A-law and µ-law selectable and employ a conventional  
serial PCM interface capable of being clocked up to  
4.096 MHz. A number of programmable functions may be  
controlled via a serial control port.  
— Transmit gain: 25.4 dB range, 0.1 dB steps  
— Receive gain: 25.4 dB range, 0.1 dB steps  
— Hybrid balance cancellation filter  
— Time-slot assignment; up to 64 slots/frame  
— 2 port assignment (TP3070)  
— 6 interface latches (TP3070)  
— A or µ-law  
— Analog loopback  
— Digital loopback  
n Direct interface to solid-state SLICs  
n Simplifies transformer SLIC; single winding secondary  
n Standard serial control interface  
n 80 mW operating power (typ)  
Channel gains are programmable over a 25.4 dB range in  
each direction, and a programmable filter is included to en-  
able Hybrid Balancing to be adjusted to suit a wide range of  
loop impedance conditions. Both transformer and active  
SLIC interface circuits with real or complex termination im-  
pedances can be balanced by this filter, with cancellation in  
excess of 30 dB being readily achievable when measured  
across the passband against standard test termination net-  
works.  
To enable COMBO II to interface to the SLIC control leads, a  
number of programmable latches are included; each may be  
configured as either an input or an output. The TP3070 pro-  
vides 6 latches and the TP3071 5 latches.  
n 1.5 mW standby power (typ)  
n Designed for CCITT and LSSGR applications  
n TTL and CMOS compatible digital interfaces  
n Extended temperature versions available for −40˚C to  
+85˚C (TP3070V-X)
