T2M Bluetooth BLE 5.3 / 15.4 RF PHY IP

BLE 5.3 / 15.4 RF PHY IP

Description and Features

The icyTRX ultra-low-power RF transceiver is designed to meet standards such as Bluetooth v5.3 Low Energy (Bluetooth Smart), 802.15.4 PHY Layer (e.g. ZigBee), and proprietary standards with data-rates from 62.5 kBit/s up to 4 Mbit/s. icyTRX offers less than 5.5mW consumption in receive mode from a 1.0V supply. icyTRX is a complete transceiver that is designed for miniaturization, yielding a die size of less than 1.6 mm2 in 55 nm CMOS, requiring minimal external components thanks to high degree of integration. icyTRX is designed for easy integration into ASICs and SoCs. Available under license as an embedded IP block for integration in CMOS SoCs and ASICs. This is a mature, production proven RF IP. Samples and development kits are available.
