ISL15102IRZ

Overview

The ISL15102IRZ is a single-port differential line driver developed for Power Line Communication (PLC) applications. It is designed to drive heavy line loads while maintaining high linearity required in Orthogonal Frequency Division Multiplexing (OFDM) PLC modem links. The device features a disable control pin (DIS) that allows entry into low-power mode with high-impedance outputs, improving Time Division Multiplexing (TDM) receive signal integrity. An internal input common-mode buffer maximizes dynamic range and reduces external component count. The IC supports narrowband and broadband DMT PLC standards and includes built-in thermal shutdown protection at +150°C typical. It operates on a single supply from +8V to +28V (absolute maximum 30V). Key electrical parameters include a 90MHz signal bandwidth, 900V/µs slew rate, -86dB THD at 200kHz into 50Ω, and -70dB THD at 3MHz into 50Ω. Output current capability is 0.75A, with 0.2A @ 50Ω load. The device is housed in a 4mm x 5mm 24-lead QFN package and specified for operation from -40°C to +105°C.

Procurement Notes

Verify the specific suffix IRZ corresponds to the RoHS-compliant, lead-free variant in the 24-lead QFN package. Confirm the operating temperature range meets the application's environmental requirements of -40°C to +105°C. Ensure the single supply voltage range of 8V to 28V aligns with the system design. Check for any recent Product Change Notices regarding labeling or packaging updates.

Selection Notes

Select this component for applications requiring high linearity and heavy load driving capability in PLC environments. The 90MHz bandwidth and 900V/µs slew rate support both narrowband and broadband DMT standards. The integrated thermal protection and disable feature simplify system design by reducing the need for external protection circuits and enabling efficient power management during TDM operations.

Part Context

The ISL15102 is part of Renesas' portfolio of analog interface products focused on power line communication. It complements other PLC components by providing the necessary physical layer interface for transmitting data over existing electrical wiring infrastructure. The device addresses the need for robust, linear drivers capable of handling the noisy and variable impedance characteristics of power lines.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Evaluate compatibility based on pinout, package dimensions (4x5mm QFN), and electrical specifications if considering alternative suppliers.
