Intersil Introduces Industry's First 3.3-V Ringing SLIC with 100-V High Battery Ringing Supply Voltage Capability
-- Small form-factor QFN package conserves board space~-- Supports elimination of 5-V supply in consumer premises equipment
IRVINE, CA, September 23, 2002 Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high performance analog and wireless networking solutions, today announced the ISL5585 series of 3.3-V ringing Subscriber Line Interface Circuits (SLICs). These new ringing SLICs are the worlds first to combine 3.3-V chip voltage with up to -100-V high battery (VBH) ringing supply voltage capability. The ISL5585 SLIC series supports the space- and cost-saving trend in broadband gateway applications to eliminate the 5-V supply in favor of a single lower-power 3.3-V chip supply. Designers can select an ISL5585 in the very small Quad Flatpack No leads (QFN) package to minimize board space requirements.
The market for broadband gateways, including cable and DSL modems, is ramping at a brisk rate. According to a recent report (MDR 2/2002) from In-Stat, the compound annual growth rate for Residential Gateways in USA markets for the period 2002 through 2005 is projected to be approximately 130 percent. This includes cable, DSL, satellite and fiber-to-the-home. To meet the needs of manufacturers in these high-growth markets, Intersil has established agreements with key industry leaders, such as Texas Instruments, Integrated Devices Technology and OKI Semiconductor, to provide complete voice solutions including reference designs and layouts. These reference designs greatly reduce manufacturers costs and time-to-market.
Intersil is maintaining its leadership in voice-interface markets by working closely with industry leaders and end-users to determine emerging needs and develop complete solutions, said Mike Althar, vice president of Intersils Analog Solutions Products. We are able to provide customers a varied selection of complete voice-interface reference designs that include CODECs and DSP ICs.
The 5-V supply elimination trend is due to space-, power- and cost-saving efforts in more complex new and next-generation broadband gateways. These include voice-enabled cable and DSL modems, where added features and interfaces compete for space and increase costs and power demand. The SLIC is one of the last system components to migrate to the lower 3.3-V supply voltage enabling designers to finally eliminate the 5-V system regulator altogether. The shedding of the 5-V supply frees up space and provides significant savings to the overall bill of materials, which creates a more cost competitive product.
ISL5585 Series
ISL5585 SLICs provide many benefits to the design and designer. The low 3.3-V chip voltage reduces power consumption and supports the move away from a costly 5-V supply in the same design. A further reduction in the overall bill of materials is realized using the ISL5585 SLICs because they provide on-chip ring waveform generation and programmable current limiting, functions usually achieved with additional circuitry. On-chip programmable transient current limiting reduces the complexity and cost of the power supply because the power supply does not have to be designed to respond to, or control, sudden transient currents caused by on-hook/off-hook changes. ISL5585 SLICs help to further conserve power, offering a mere 65-mW standby consumption (at -75 VBH).
Other benefits of the ISL5585 series include tip-open ground start operation to support Foreign Exchange Station (FXS) interfaces and balanced or unbalanced ringing to accommodate legacy PBX trunks. The ISL5585 series SLICs are available in both the 28-lead PLCC package and the very small 32-pad QFN package. The 7 X 7 mm QFN package offers significant space savings along with much greater thermal efficiency. The ISL5585EVAL1 evaluation board and application note are available.
