Using advanced switched capacitor techniques 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. 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. 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. 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 CO CI CCLK CS MR BCLK MCLK DX0 DX1 TSX0 TSX1 FSX IL5 IL4 IL1 IL0 VCC VFXI Function Ground Input (+0V) Analog Output Supply Input (-5V) Not Connected Not Connected Digital Input or Output defined by LDR register content Digital Input or Output defined by LDR register content Digital input Digital input sampled by BCLK falling edge Digital input sampled by BCLK falling edge Digital output (shifted out on CCLK rising edge) Digital input (sampled on CCLK falling edge) Digital input (clock) Digital input (chip select for CI/CO) Digital Input Digital input (clock) Digital input Digital output clocked by BCLK rising ed.
