Documentation Errata for ADSP-BF535:嵌入式处理器数据手册

Change

The timing specifications for tDDTTE and tDDTTI are not properly documented in Table 22 of the Data sheet. The two specs are only applicable when the SPORT is in Multichannel mode. Also, when in multichannel mode, SPORT TSCLK is internally connected to RSCLK. Therefore, Page 31, Table 22, should read as follows .

Serial Ports - Enable and Three-State
Parameter Min Max Unit
Switching Characteristics
tDTENE Data Enable Delay from External TSCLKx1 3 ns
tDDTTE Data Disable Delay from External TSCLKx1, 2, 3 12 ns
tDTENI Data Enable Delay from Internal TSCLKx1 2 ns
tDDTTI Data Disable Delay from Internal TSCLKx1, 2, 3 12 ns

(1) Referenced to drive edge.

(2) Applicable to multichannel mode only.

(3) TSCLKx is tied to RSCLKx.

Related Signal Chains

A signal chain is a series of signal-conditioning electronic components that receive input (data acquired from sampling either real-time phenomena or from stored data) in tandem, with the output of one portion of the chain supplying input to the next. Signal chains are often used in signal processing applications to gather and process data or to apply system controls based on analysis of real-time phenomena. For more information about this term and related topics, see the "signal chain" entry in Wikipedia or the Glossary of EE Terms on the Analog Devices website.

Analog Devices eases signal processing system development by providing signal processing components that are designed to work together well. A tool for viewing relationships between specific applications and related components is available on the www.analog.com website.

The Application Signal Chains page in the Circuits from the Labtm site (http:\\www.analog.com\signalchains) provides:

  • Graphical circuit block diagram presentation of signal chains for a variety of circuit types and applications

  • Drill down links for components in each chain to selection guides and application information

  • Reference designs applying best practice design techniques
