OOK receiver balances performance, power draw, BOM

Integration Associates has unveiled the newest addition to its EZRadio product family: the IA4315 OOK (ON/OFF keying) wireless receiver. The IA4315 is a low-cost, OOK receiver designed specifically for 434/868/915MHz band applications such as toy, home automation and building products.

The IA4315 is designed to provide the optimal balance between BOM, design flexibility, performance and current consumption. Additionally the IA4315 provides users with the usual EZRadio features such as a built-in low-battery detector, wake-up timer, MCU clock-out, a 64bit Rx FIFO and a programmable baseband bandwidth to accommodate various deviation, data rate and crystal tolerance requirements.

Designed to operate between 2.2V and 3.8V using one crystal and a couple of external decoupling capacitors, the IA4315 promises the lowest-cost OOK receiver on the market. It is also designed to reduce load on the external MCU. Integrated digital data processing such as data filtering, clock recovery and data pattern recognition reduce the need for higher-end MCUs in favor of small low-cost 4/8bit variants.

"The short-range ISM market is currently dominated by proprietary solutions, and as such has a wide range of different radio alternatives," commented Rafi Fried, general manager for Integration's wireless business unit. "Although most new applications today are 2-way FSK transceiver based, there is a large install base of mostly legacy, 1-way OOK type applications. Integration's goal in general is to provide the most suitable solution to every short-range ISM application and the IA4315 is targeted to provide the lowest BOM cost solution with state-of-the-art performance for those 1-way link OOK customers."
