Low Power Ringing SLIC for Home Gateways
The ISL5586 is a very low power Ringing Subscriber Interface circuit designed for use with the Broadcom
BCM3352 Cable Modem Chip, with on-board voiceband codecs, or other 3.3V voiceband codec devices.
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.
Together with the Broadcom BCM3352, the ISL5586 provides resistive and complex two wire impedance matching and transhybrid balancing. Also supported are on­hook 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.
