Product Summary
The IDT82V1074PF is a RSLIC-CODEC chipset comprised of one four-channel programmable PCM CODEC and four single-channel ringing SLIC. The IDT82V1074PF provides a total solution for line card designs. In addition to providing a complete software programmable solution for BORSCHT, additional functions such as FSK generator, Universal Tone Detection (UTD) unit, tone generators, ringing generator, Integrated Test and Diagnosis Functions (ITDF), line polarity reversal and three-party conference are integrated in to the chipset. The high integration of system functions reduces board space requirements of the line card and saves cost.
