(1) to improve emi on the lfxt oscillator, observe the following guidelines: ? keep the trace between the device and the crystal as short as possible. ? design a good ground plane around the oscillator pins. ? prevent crosstalk from other clock or data lines into oscillator pins xin and xout. ? avoid running pcb traces underneath or adjacent to the xin and xout pins. ? use assembly materials and processes that avoid any parasitic load on the oscillator xin and xout pins. ? if conformal coating is used, make sure that it does not induce capacitive or resistive leakage between the oscillator pins. (2) when lfxtbypass is set, lfxt circuits are automatically powered down. input signal is a digital square wave with parametrics defined in the schmitt-trigger inputs section of this data sheet. duty cycle requirements are defined by dc lfxt, sw . (3) maximum frequency of operation of the entire device cannot be exceeded. (4) oscillation allowance is based on a safety factor of 5 for recommended crystals. the oscillation allowance is a function of the lfxtdrive settings and the effective load. in general, comparable oscillator allowance can be achieved based on the following guidelines, but should be evaluated based on the actual crystal selected for the application: ? for lfxtdrive = {0}, c l,eff = 3.7 pf ? for lfxtdrive = {1}, 6 pf c l,eff 9 pf ? for lfxtdrive = {2}, 6 pf c l,eff 10 pf ? for lfxtdrive = {3}, 6 pf c l,eff 12 pf (5) includes parasitic bond and package capacitance (approximately 2 pf per pin).

important notice texas instruments incorporated (ti) reserves the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per jesd46, latest issue, and to discontinue any product or service per jesd48, latest issue. buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. ti ? s published terms of sale for semiconductor products ( http://www.ti.com/sc/docs/stdterms.htm ) apply to the sale of packaged integrated circuit products that ti has qualified and released to market. additional terms may apply to the use or sale of other types of ti products and services. reproduction of significant portions of ti information in ti data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. ti is not responsible or liable for such reproduced documentation. information of third parties may be subject to additional restrictions. resale of ti products or services with statements different from or beyond the parameters stated by ti for that product or service voids all express and any implied warranties for the associated ti product or service and is an unfair and deceptive business practice. ti is not responsible or liable for any such statements. buyers and others who are developing systems that incorporate ti products (collectively, ? designers ? ) understand and agree that designers remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that designers have full and exclusive responsibility to assure the safety of designers ' applications and compliance of their applications (and of all ti products used in or for designers ? applications) with all applicable regulations, laws and other applicable requirements. designer represents that, with respect to their applications, designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and take appropriate actions. designer agrees that prior to using or distributing any applications that include ti products, designer will thoroughly test such applications and the functionality of such ti products as used in such applications. ti ? s provision of technical, application or other design advice, quality characterization, reliability data or other services or information, including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, ? ti resources ? ) are intended to assist designers who are developing applications that incorporate ti products; by downloading, accessing or using ti resources in any way, designer (individually or, if designer is acting on behalf of a company, designer ? s company) agrees to use any particular ti resource solely for this purpose and subject to the terms of this notice. ti ? s provision of ti resources does not expand or otherwise alter ti ? s applicable published warranties or warranty disclaimers for ti products, and no additional obligations or liabilities arise from ti providing such ti resources. ti reserves the right to make corrections, enhancements, improvements and other changes to its ti resources. ti has not conducted any testing other than that specifically described in the published documentation for a particular ti resource. designer is authorized to use, copy and modify any individual ti resource only in connection with the development of applications that include the ti product(s) identified in such ti resource. no other license, express or implied, by estoppel or otherwise to any other ti intellectual property right, and no license to any technology or intellectual property right of ti or any third party is granted herein, including but not limited to any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which ti products or services are used. information regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or endorsement thereof. use of ti resources may require a license from a third party under the patents or other intellectual property of the third party, or a license from ti under the patents or other intellectual property of ti. ti resources are provided ?
