The bq2003 is a fast-charge IC that provides comprehensive fast-charge control functions and high-speed switching power-control circuitry on a monolithic CMOS device. This application note describes t
The TMS320DM6446 device has a rich set of peripherals; however many of these peripherals are multiplexed with each other and only one is available at a time.
Perhaps the best example of a multiplexing scenario found on the TMS320DM6446 device is the asynchronous external memory interface (EMIFA). The pins that make up this interface are multiplexed to service NAND flash NOR flash CF hard
Certain applications require the TMS320C30's high arithmetic throughput in the IEEE floating-point format. These applications benefit from a custom chip that performs conversions between the TMS320C30 native format and the single-precision IEEE Standard 754-1985. This chapter describes this custom chip.The description includes the following specific topics:- External interfaces- Arch
Time-Base Oscillator for RTC ICs.The operation of the time-base oscillator is critical to the timekeeping functions of the bq3285 bq4285 and bq4845 series of real-time-clocks (RTCs). This application note describes some basic characteristics of the piezoelectric crystal and the on-chip crystal oscillator circuitry designed into these RTC series. It also includes suggestions for achieving timek
This application report provides several design examples of high-performance applications using theLME49710/LM4562 that demonstrate their capability in meeting the demands of the highest audibleperformance.
This application note describes how system designers can interface the TMS320VC5420 16-bit HPI (C5420) to the PCI bus using the TMS320C6x HPI (C6x) mode interface on the PCI2040 PCI-to-DSP bridge. The note specifies two modes for mapping the C5420 to host memory depending on the number of C5420s. The note also describes both hardware and software considerations provides an example schematic an
At Burr-Brown, we characterize and qualify the reliability of our devices through high temperature life testing. The results of this testing are quantified with such values as MTTF and failure rate. T
The TPS23753A is intended for isolated applications and does not incorporate an internal voltage-regulation error amplifier. Due to its integration and features it may be advantageous to use the TPS23753A in non-isolated applications. This application report shows additional circuits necessary to implement a low-side switch buck converter using the TPS23753A.
This application report describes design considerations for low-voltage differential swing (LVDS) multidrop connections. The report describes the maximum number of receivers possible versus signaling rate signal quality line length output jitter and common-mode voltage range when multidrop testing on a single LVDS line driver transmitting to numerous daisy-chained LVDS receivers.The LVDS rec
