STMicroelectronics TS5070

the TS5070 and TS5071 combine 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. Both transformer and active SLIC interface circuits with real or complex termination impedances can be balanced by this filter, with cancellation in excess of 30 dB being readily achievable when measured across the passbandagainst standardtest termination networks.

DESCRIPTION

The TS5070series are the second generationcombined PCM CODEC and Filter devices optimized for digital switching applications on subscriber and trunk line cards. Using advanced switched capacitor techniques A number of programmable functions may be controlled via a serial control port. December 1997 DIP20 (Plastic) ORDERING NUMBER: TS5071N PLCC28 ORDERING NUMBERS: TS5070FN TS5070FNTR Channel gains are programmable over a 25.4 dB range in each direction, and a programmable filter is included to enable Hybrid Balancing to be adjusted to suit a wide range of loop impedance conditions. To enable COMBO IIG 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 TS5070 provides 6 latches and the TS5071 5 latches. 1/32 TS5070 - TS5071 TS5070 PIN FUNCTIONALITY (PLCC28) No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 Name GND VFR0 VSS NC NC IL3 IL2 FSR D R1 D R0...
