CYW20737LT

CYW20737LT is a low-power, low-cost single-chip dual-mode radio transceiver IC developed by Cypress Semiconductor for Bluetooth low energy, Bluetooth 5.0, 802.15.2 and Zigbee compatible applications. It provides industry leading power performance, range, and flexibility with a feature-rich and fully integrated solution that uses minimal external components. The CYW20737LT provides an integrated RF transceiver, baseband controller and MCU with integrated power management. It is optimal for applications that require long battery life, and is the ideal solution for wearable applications.

The main features of CYW20737LT are:

1. Integration of radio, baseband controller, MCU and power management system.
2. Ultra low power consumption with ultra effective power management.
3. Integrated high-performance SEP2.0 feature for energy friendly extension.
4. An integrated radio with up to 30dBm of output power for longer range operation.
5. Multi-standard support for Bluetooth low energy, Bluetooth 5.0, 802.15.2 and Zigbee compatible applications.
6. Enriched integrated integration of advanced host interface, on-board memory, and development tools.

The CYW20737LT has four main blocks: a Digital Baseband CPU (BB), a Digital Radio CPU (RF), a Baseband Interface (BB Interface), and a Radio Interface (RF Interface). In addition to these, the CYW20737LT also includes a power management system, a Bluetooth low energy network processor, a Bluetooth access controller, and a Bluetooth low energy controller.

The BB CPU is responsible for the task of demodulation and encoding of the radio transmission. The RF CPU governs the RF transmission chain and is responsible for the task of modulation and encoding. The BB Interface contains a controller and numerous analog components that manage the control of baseband protocol layers. The RF Interface is the physical connection between the transceiver IC and external radio hardware which carries out the filter, amplification, and modulation/demodulation operations of the signals.

The CYW20737LT is used in many products including wearables, consumer electronics, audio products, building control, Zigbee, etc. It is mainly used for developing wireless applications with low power consumption and long battery life. It is also used for Bluetooth beacon applications where it acts as a bridge between the device and a cloud server, transmitting Bluetooth and Beacon data over long ranges.

In its operation, the CYW20737LT uses a number of technologies to ensure the highest efficiency and most reliable performance. These include signal pre-processing and equalization, frequency fine-tuning for wider coverage, digital noise cancellation, and packet and frame error checking. These features all help reduce the power and spectral efficiency of the IC while increasing the reliability and performance of communications.
