Low Power Ringing SLIC for Home  
Gateways  
Features  
• Interfaces to Broadcom 3352 cable modem device  
• Very low on-hook power consumption  
- 64mW @ Vbh = 75V  
The ISL5586 is a very low  
power Ringing Subscriber  
Interface circuit designed for  
• User Programmable constant current to the subscriber  
loop  
use with the Broadcom*  
BCM3352 Cable Modem  
• On Chip ring generation  
Chip, with on-board voiceband codecs, or other 3.3V  
voiceband codec devices.  
- Balanced to 95 Vpk  
• Sinewave, Trapezoid, DC offset  
• Programmable loop start and ring trip detectors  
• Loop start, Ground Start, Polarity Reversal (soft/hard)  
• On-Hook transmission and pulse metering support  
• Integrated battery switch  
The ISL5586 provides on board ringing signal generation up  
to 95V peak supporting sinusoidal or trapezoidal  
waveshapes with DC offset. Loop start and ground start  
trunks are supported, and an open circuit DC voltage of less  
than 56V is maintained on the subscriber loop in the on-hook  
condition, in compliance with MTU operation and the safety  
requirements of UL-1950.  
• Open circuit line voltage clamp  
• Compatible with 3.3V devices  
• TR-57 compliant Longitudinal balance  
• 28 PLCC packaging  
Together with the Broadcom BCM3352, the ISL5586  
provides resistive and complex two wire impedance  
matching and transhybrid balancing. Also supported are on-  
hook transmission of caller id signals, soft and hard polarity  
reversal and 12/16kHz subscriber pulse metering systems  
used in Europe and Asia, thereby allowing a low cost, low  
risk, global product design to be achieved.  
• Latch-up free Bipolar design  
• Thermal protection  
Applications  
• Cable Modems  
• Voice Over DSL (VoDSL)  
• Broadband Wireless Access  
• Voice Over Internet Protocol (VoIP)  
• ISDN Terminal Adapters (TA)  
• Small Office Home Office PBX  
• Wireless Local Loop
