DESCRIPTION  
The Le58QL022 Quad Low Voltage Subscriber Line Audio-  
Processing Circuit (QLSLAC™) devices integrate the key  
functions of analog line cards into high-performance, very-  
programmable, four-channel codec-filter devices. The  
QLSLAC devices are based on the proven design of Legerity’s  
reliable SLAC™ device families. The advanced architecture of  
the QLSLAC devices implements four independent channels  
and employs digital filters to allow software control of  
transmission, thus providing a cost-effective solution for the  
audio-processing function of programmable line cards. The  
QLSLAC devices are software and coefficient compatible to the  
QSLAC devices.  
— Transhybrid balance  
— Transmit and receive gains  
— Equalization (frequency response)  
— Digital I/O pins  
— Programmable debouncing on one input  
— Time slot assigner  
— Programmable clock slot and PCM transmit clock edge  
options  
„ Standard microprocessor interface  
„ A-law, µ-law, or linear coding  
„ Single or Dual PCM ports available  
— Up to 128 channels (PCLK at 8.192 MHz) per PCM port  
— Optional supervision on the PCM highway  
Advanced submicron CMOS technology makes the  
Le58QL022 QLSLAC devices economical, with both the  
functionality and the low power consumption needed in line  
card designs to maximize line card density at minimum cost.  
When used with four Legerity SLIC devices, a QLSLAC device  
provides a complete software-configurable solution to the  
BORSCHT functions.
