The Si3050 extends the market-leading performance of Silicon Laboratories’
silicon Direct Access Arrangement (DAA) products into the voice telephony
market.
The chipset features a small footprint which consists of a 20-pin Si3050
(TSSOP) system-side device and either the 16-pin Si3019 (TSSOP) or the 16-pin
Si3018 (SOIC) line-side device. The solution utilizes Silicon Labs' patented
capacitive isolation technology that uses low-cost, high voltage capacitors
instead of a costly and bulky transformer. The Si3050 contains both a PCM
highway/SPI interface for most standard telephony applications as well as a
GCI interface for customers with legacy requirements. The line-side devices
are fully programmable to meet global telephone line standards (FCC, CTR-21,
NET4, JATE, and many others) using a single bill-of-materials and PCB design.
Also offered are a host of new features that provide unparalleled
functionality to the designer, including up to 16 software selectable AC
terminations, a programmable hybrid to allow adjustment to real world line
conditions, and the ability to gain or attenuate transmit/receive line signals
in increments of 0.1 dB.
