Product Details Supplier Info More products

ON Semiconductor, a supplier of high-performance, energy-efficient silicon solutions, has introduced the AMIS-49587, the latest member of its power line carrier (PLC) modem family.

The AMIS-49587 provides a highly integrated, standard compliant, low-power PLC solution for use in applications such as smart electric automatic meter reading and management, street-lighting control, smart power plugging and building automation.

Utilising the company’s mixed-signal technology allows the AMIS-49587 to combine both the analogue modem front end and digital post-processing capability in the same integrated circuit.

By offering an integrated single-chip solution, the IEC1334-compliant AMIS-49587 helps to simplify designs, lower development and implementation costs and speed time to market.

This device is based around an ARM7TDMI processor core and includes both the physical interface transceiver (PHY) and the media access controller (MAC) layers.

Using the spread frequency shift keying (S-FSK) modulation technique coupled with accurate filtering gives low-data-rate communications on power lines over long distances.

Half-duplex selectable communication speeds of 2,400 bits per second (baud) can be achieved.

A low operating frequency of less than 20kHz with an automatic repeater function further supports dependable communications with fewer communication errors than alternative and existing solutions.

Synchronisation to the mains signal is done via an onboard low-jitter PLL, while an embedded filter provides white noise and narrowband interference rejection.

Direct connection to the host MCU is via a two-wire serial interface.

As a result of its high level of integration and the onboard protocol embodiment, the AMIS-49587 accepts high-level data inputs and eliminates the need for designers to go into PHY and MAC protocol transmission details.

This higher-level interface means that up to 50 per cent of the software development effort can be saved, leading to a shorter time to market and reduced overall cost.

Supplied in a PLCC 28 package, the lead-free and RoHS-compliant AMIS-49587 is pin compatible with the AMIS-30585: ON Semiconductor’s existing half-duplex S-FSK modem.

The operating temperature range for the AMIS-49587 is -40C to +80C.

The company will soon offer the AMIS-49587 in a QFN package.

The AMIS-49587 is currently available and budgetary pricing is USD11.00 (GBP6.77) for quantities of 1,000 units and above.

AMIS-49587 evaluation kits are also available.
