The ISL1572 is a dual operational amplifier designed for PLC line driving in OFDM and SSC based solutions. This device features a high drive capability of 750mA while consuming only 6mA of supply current per amplifier and operating from a single 4.5V to 12V supply. The driver achieves a typical distortion of -80dBc, at 150kHz into a 25Ω load. The ISL1572 is available in the thermally-enhanced 16 Ld QFN or 10 Ld HMSOP package and is specified for operation over the full -40°C to +85°C temperature range. The ISL1572 has control pins BIAS0 and BIAS1 for controlling the bias and enable/disable of the outputs. These controls allow for lowering the power to fit the performance/power ratio for the application.

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 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.

The 3.3V family of ringing subscriber line interface circuits (SLIC), ISL5585, supports analog Plain Old Telephone Service (POTS) in short and medium loop length, wireless and wireline voice over broadband applications. Ideally suited for customer premise equipment, this family of products offers flexibility to designers with high ringing voltage and low power consumption system requirements. The ISL5585 family is capable of operating with 100V ringing battery supply, which translates directly to the amount of ringing voltage supplied to the subscriber. With the high operating voltage, subscriber loop lengths can be extended to 500Ω (i.e., 5,000 feet) and beyond, allowing this family to serve emerging Fiber In The Loop (FITL) markets. Other key features across the product family include: 3.3V VCC operation, low power consumption, ringing using sinusoidal or trapezoidal waveforms, robust auto-detection mechanisms for when subscribers go on or off hook, and minimal external discrete application components. Integrated test access features are also offered on selected products.

The HC5503T is a low cost Subscriber Line Interface Circuit (SLIC) from Intersil that replaces the components of a discrete Transformer Analog circuit design. The monolithic integrated design provides improved performance and system reliability. The HC5503T provides: Current limited DC feed to the subscriber loop, maintains a flat frequency response over the voice band and beyond, has self resetting thermal protection that allows conversation to continue while the fault is present, provides a TTL subscriber off hook indication even in the presence of longitudinal currents, and limits system power consumption on short loops. The HC5503T provides balanced 2-wire transmission and has excellent longitudinal balance, while providing on hook transmission and longitudinal current rejection in both the on-hook or off-hook conditions. The SLIC needs only one +5V supply in addition to the main battery supply for loop current and operates over a range of battery voltages (-24V to -58V). Available in 24SO packaging. The HC5503T is ideally suited as a replacement for discrete line circuits in low cost analog PABXs, small Office/Home Office products or Small Key Systems.

The HC5526 is a subscriber line interface circuit that is compliant with CCITT standards. Enhancements include immunity to circuit latch-up during hot plug and absence of false signaling in the presence of longitudinal currents. The HC5526 is fabricated in a High Voltage Dielectrically Isolated (DI) Bipolar Process that eliminates leakage currents and device latch-up problems normally associated with Junction Isolated (JI) ICs. The elimination of the leakage currents results in improved circuit performance for wide temperature extremes. The latch free benefit of the DI process guarantees operation under adverse transient conditions. This process feature makes the HC5526 ideally suited for use in harsh outdoor environments.
