TS5070 series

The TS5070 series are second generation combined PCM CODEC and filter device optimized for digital switching applications on subscriber and trunk line cards.Using advanced switched capacitor techniques the TS5070 and TS5071 combine transmit bandpass and receive lowpass channel filter with a companding PCM encoder and decoder.The devices are A-law and u-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.channel gain are programmable over a 25.4 dB range in each direction,and a programmable filter is included to enable hybrid balabcing 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 passband against standard test termination network.

The absolute maximum ratings of the TS5070 series can be summarized as:(1)Vcc to GND:7 V;(2)Vss to GND:-7 V;(3)voltage at VFXI:Vcc+0.5 to Vss-0.5 V;(4)voltage at any digital input:Vcc+0.5 to GND-0.5 V;(5)current at VFRO:+/-100 mA;(6)current at any digital output:+/-50 mA;(7)storage temperature range:-65 to +150;(8)lead temperature range(soldering,10 seconds):300.
