National Semiconductor Corporation today announced its newest Bluetooth product family that complies with the recently ratified Bluetooth Specification Version 1.2.
The LMX5252 is a Bluetooth radio transceiver that delivers the highest level of RF integration available today. The LMX5452 combines the radio with an enhanced Bluetooth 1.2 baseband processor into a small micro-module package. Both products offer a high level of analog and RF integration in a small footprint, saving space and cost while enhancing performance.
"National's LMX5452 micro-module packaging technology, combined with the increased level of radio integration, makes this new Bluetooth product family a superior solution for mobile phone and computing applications," said Malcolm Humphrey, director of National's Device Connectivity Division. "What customers care about is the size of the solution and ease of design. Using National's micro-module solution reduces RF board complexity, enabling mobile device manufacturers to integrate the device directly onto their main board design, and reducing the need for a traditional and more expensive module approach."
Bluetooth wireless technology enables users to exchange information between a wide variety of computing and communications systems, including mobile phones, PCs, printers, PDAs, and even your automobile, without connecting wires or cables. The new features found in Bluetooth Specification Version 1.2 include faster connecting times, improved voice transmissions and adaptive frequency hopping (AFH) for improved coexistence of Bluetooth with other 2.4GHz devices.
The LMX5252, in a 36-pin LLP package measuring 6mm by 6mm by 0.8mm, is a highly integrated .18 micron CMOS Bluetooth radio transceiver with an integrated Tx/Rx switch and baluns. It supports multiple system clock frequencies of 10 to 40MHz, and has a typical Rx sensitivity of -84dBm. The LMX5252 is ideal for applications where Bluetooth baseband functionality is already integrated into the primary processor, including systems using National's CP3000 connectivity processors.
The LMX5452, in a 64-pin micro-module BGA package measuring 9mm by 6mm by 1.2mm, combines the Bluetooth transceiver with a baseband processor. The baseband processor features full Bluetooth 1.2 functionality and firmware, and an enhanced HCI command structure. In addition, it combines on-chip, ROM-based memory with a seamless memory patch controller and flexible patch RAM.
