Cypress's PSoC® 3 Device Enables TEAC Corporation's Microphone Accessories to Deliver Bit-Perfect Digital Audio with iPhone, iPad, and iPod touch
Programmable Solution Streamlines Design of High-Quality, Digital Audio Interface With Apple iOS Devices; Handles Proprietary MFi Protocol
The iM2, iM2X, and iXJ2 plug into Apple's dock connector for iOS devices. The iM2 and iM2X each feature a pair of condenser microphones that are adjustable over 180 degrees for optimal sound capture, and they each contain a preamp that can handle up to 125 decibels for the loudest concerts and instruments. The iXJ2 provides two microphone or line inputs that can be used individually or in tandem for stereo recordings, making it ideal for video capture. Each accessory is powered by the connected iOS device and works with TASCAM's PCM Recorder iOS app, Apple's GarageBand, and other Core Audio compatible recording apps.
Cypress's PSoC 3 MFi digital audio solution manages the interface between the TASCAM accessories and any iOS device via Apple's dock connector. The designs leverage PSoC 3 to provide pristine audio recording, as well as simultaneous playback. With Cypress's patent-pending clock synchronization and recovery scheme, PSoC 3 ensures no samples are dropped, delivering the highest quality digital audio with minimal external components at multiple audio sample rates (at standard intervals up to 24-bit audio, 48-kHz sampling rate). More information about Cypress's clock synchronization and recovery scheme is available at www.cypress.com/?docID=25374.
"With PSoC 3's flexible architecture and drag-and-drop MFi
compatibility, we developed the iM2, iM2X, and iXJ2 to put high-quality
audio recording capabilities into the hands of iPhone and iPad users,"
"PSoC provides designers with a quick, inexpensive, fully-tested
solution for accessories using Apple's proprietary MFi interface," said
PSoC — Because Change Happens
PSoC devices employ a highly configurable system-on-chip architecture for embedded control design, offering a flash-based equivalent of a field-programmable ASIC without lead-time or NRE penalties. PSoC devices integrate configurable analog and digital circuits, controlled by an on-chip microcontroller, providing both enhanced design revision capability and component count savings. A single PSoC device can integrate as many as 100 peripheral functions saving customers design time, board space and power consumption while improving system quality and reducing system cost.
The new PSoC 3 and PSoC 5 architectures include high-precision programmable analog capability (up to 20-bit resolution for an Analog to Digital Converter) and expanded programmable digital resources integrated with powerful, industry-standard MCU cores and ample memory and communications peripherals. PSoC 3 devices are based on a high-performance, 8-bit 8051 processor, while PSoC 5 devices include a powerful 32-bit ARM Cortex-M3 processor. The products provide designers with a seamless, programmable design platform, enabling easy migration from 8 to 32 bits. The robust features of these new solutions dramatically expand the applications and markets that PSoC can address, including automotive, portable medical, industrial, and many more. The PSoC 1 family is based on a cost-optimized 8-bit M8C core. More information about PSoC products is available at www.cypress.com/psoc and free online training is at www.cypress.com/psoctraining.
