Freescale i.MX27 IP Camera Reference Design block diagram


  • Innovative IP camera design is powered by the high-performing, low-power Freescale i.MX27 multimedia applications processor
  • H.264 and MPEG-4 video compression, optimized for performance and power (dual-stream capable)
  • Aptina 2 MP CMOS sensor with integrated ePTZ
  • High quality Tamron CS-mount lens with manual iris
  • Wired or wireless (802.11g) streaming
  • Power-over-Ethernet (POE) enabled
  • Embedded web server with client setup page for camera configuration and remote viewing
  • Royalty-free reference design
  • Comprehensive software and hardware design package enables OEM customization or can be taken direct to manufacture

Freescale’s hardware-optimized reference design is engineered to allow OEMs and ODMs to easily differentiate their own IP cameras with added features, instead of focusing on core hardware/software design. The Freescale IP camera reference design implements the “must have” features for IP network cameras, beginning with H.264 compression technology to minimize network bandwidth and provide outstanding image quality. Other features include low-power operation, Power-over-Ethernet (POE) technology for seamless integration into existing networks, and D1 resolution image compression for sharp image detail and fast intruder identification.

In addition to IP network cameras, the i.MX27 reference design targets the video and voice over IP (V2IP) market and can be used to create applications such as household doorbell products and consumer baby monitor devices. Consumers may view an enhanced live video feed – from their office, mobile or other connected product – allowing them to remotely track home security and receive email status notifications when a potential threat is detected. The design is ideal for V2IP applications requiring a camera, high-performance video compression, low-power operation and wired or wireless connectivity.

CSR BlueVox2 Mono Bluetooth Headset

CSR recently released a BlueVox2 mono headset solution that costs only $5. BlueVox2 features extremely low power consumption and zero cost noise reduction. CSR’s design features AuriStream for superior voice quality, simultaneous connection of multiple devices, and support for Bluetooth version 2.1+EDR. BlueVox2 also presents headset manufacturers with the opportunity to design the smallest Bluetooth headsets through an ultra small 4.5×5.5mm BGA package option. CSR is currently sampling BlueVox2, with first headsets expected to be in the shops by Q308.

The reference design includes the BlueVox2 QFN chip, and all the components necessary for a Bluetooth mono headset mounted on a four-layer printed circuit board. BlueVox2 is power efficient — permitting 15 hours talktime with a small 120mAh battery. BlueVox2′s range of features also includes hardware-based noise reduction technology at no extra cost. CSR’s all inclusive eBOM helps OEMs keep their costing simple and predictable.

The design also raises voice quality to the standard of a landline phone by using CSR’s AuriStream CODEC. AuriStream delivers an ITU-T mean opinion score (MOS) of up to 4.2 out of 5, even without the additional benefits of noise reduction. In comparison, headsets using only the more standard CVSD CODECs achieve a MOS of around 2.46. Calls made using AuriStream are of noticeably better quality.

BlueVox2 is the first ever ROM headset design to allow two or more Bluetooth devices to be connected to the same headset. This means that with one headset it is possible to take calls from both a work and personal phone or a phone and a VoIP dongle. The feature doesn’t impact the power consumption and is designed to be easy and intuitive to use.

BlueVox2 is the first ROM to adhere to Bluetooth v2.1+EDR, offering Secure Simple Pairing, which greatly simplifies the headset-to-phone pairing process while significantly increasing Bluetooth device security. With the enhanced inquiry scan Bluetooth v2.1 can also gather and present a greater range of information when searching for devices, including a list of services each device supports.

BlueVox2 integrates onto a single chip the world’s leading Bluetooth radio design, CODECs for the microphone and speakers, power management, a battery charger and a microprocessor to run virtual machine applications. BlueVox2′s silicon, based on CSR’s BlueCore6-Audio ROM, features a low cost 7x7mm QFN package as well as a 4.5×5.5mm BGA package option for the world’s smallest headset IC. The performance of BlueVox2′s radio is exemplary, with TX+8dBm and Rx -90Bm helping to overcome cross-body issues and increase range.

BlueVox DSP eBOM Bluetooth Mono Headset Design

CSR’s BlueVox DSP is a low cost $6 eBOM Bluetooth mono headset design with enhanced DSP based Clear Voice Capture (CVC) echo and noise cancellation technology. BlueVox DSP is the first ROM-based solution with an integrated DSP coprocessor and features AuriStream, CSR’s low power voice CODEC for superior quality voice calls. With a bill of materials of just $6, CSR has designed BlueVox DSP with the richest feature set including single and dual microphone noise suppression and support for simultaneous connection to two devices. Compared to competitive solutions BlueVox DSP offers far superior audio performance and lower power consumption through its advanced DSP architecture and CVC noise cancellation, while maintaining an ultra low $6 eBOM, previously only achieved for basic low cost mono headset designs.

The $6 reference design includes all the necessary hardware and software components, including CSR’s proprietary CVC software. With the single microphone echo and noise suppression algorithm included and a licensed option to upgrade to the new dual microphone algorithm for superior noise suppression, being heard, whatever the surrounding noise is no longer a problem. The solution also incorporates AuriStream, CSR’s high quality low power voice CODEC that provides a fixed line quality connection and is capable of a 30% reduction in power consumption compared with standard Bluetooth voice transmission methods.

Based on CSR’s proven BlueCore5-Multimedia platform, BlueVox DSP benefits from the industry’s lowest cost and highest performance figures. BlueCore5-Multimedia features a best in class audio CODEC with a signal to noise ratio of -95dB. The radio transmits at +8dBm and receives at -90dBm, which eliminates any interference and enhances range when taking a call.

BlueVox DSP supports v2.1 +EDR of the Bluetooth specification, offering significant enhancements to the end user experience for secure and simple pairing between devices. This solution also includes support for multiple connections, allowing a user to take calls from two mobile phones or a mobile phone and a VoIP dongle through a simple user interface.

The BlueVox DSP features a compact 4 layer PCB reference design and is available in both 8x8mm QFN and compact 7x7mm BGA package options. The 7x7mm BGA package option allows easy migration from BlueCore5-Multimedia Flash, for designers wishing to further reduce cost for their high-end mono headset designs. CSR’s BlueVox DSP is available now, and headsets based on BlueVox DSP are expected to be on the market later this year.
