与其他三名名模相比,秦舒培相对弱势,毕竟近年来她的作品并不多,而且出镜率也不高。2012凤凰时尚之选时尚领袖大奖?2011ELLE风尚大典国际超模新秀?2010ELLE风尚大典年度风尚超模?2009中国风尚超模颁奖典礼潜力超模大奖这些是近年秦舒培获奖情况,但是都是几年前了。之后参加的有名气的活动不多,也让她的名气开始下滑。相比之下,刘雯、奚梦瑶和何穗,自上次参加了维密之后,人气依然很高,而且持续上涨。如果你是维密的评委,你会怎么选择呢!且不说其他的,前段时间香奈儿的活动,国内众多明星都参加了,刘雯大表姐也是其一,可见名气不减当年。再说下何穗,不管是街拍还是电视活动,近期都不少。据说这是东方卫视

谢贤不准王菲进家门有以下几个原因:首先,谢贤对张柏芝这个媳妇的满意和对王菲的偏见。谢贤明确表示,谢家的儿媳妇只认张柏芝,即使跟谢霆锋离了婚也还是经常带着儿子去见前公公,给前公公贺寿!而谢贤也对两个孙子宠爱的不行!爷爷和孙子亲是毋庸置疑的,血浓于水,爱屋及乌,自然也是对悉心照顾两个孩子的张柏芝很有好感,他内心里一直是希望自己儿子和张柏芝能够和好,也是为了两个孙子着想,希望两个孙子能够在一个完整的家庭长大。而对离过两次婚的王菲可能就没什么感情了!曾有记者采访谢贤的时候,想旁敲侧击的问一下对王菲的态度,问了一句:跟王菲熟么?谢贤直接就回了一句:跟你爹熟一点!这很明显就是都不想提到王菲啊!王菲她的年龄

经常从电视剧里看到空姐拖着箱包行走在候机楼中,看起来既光鲜、又神秘,最好奇的是箱子里面究竟放了些什么呢?从我朋友那了解到,在当天来回的短途飞行中,一个小箱子和一个小拎包是标准装备。先说说小拎包,这可是麻雀虽小五脏俱全。首当其冲的就是乘务员的化妆包,一个精致职业的妆容必定离不开及时的补妆。飞机过站时、用餐完毕后乘务员都会稍加补妆,以最饱满的精神面貌再一次展现在旅客面前。除了私人物品外,还有很多乘务员为旅客着想的小物件,比如说邦迪、指甲刀、风油精、蚊不叮、针线包,小到一根牙签等等。乘务员像小叮当一样,能\"变\"出很多旅客所需要的东西。当然乘务员上机所需的各种证件也是小拎包中的必需品,譬如登机证、

Description

The VCO600A is a SAW stabilized, voltage controlled oscillator that operates at the fundamental frequency of the internal SAW filter. This filter is a high stability, high-Q quartz device that enables the circuit to achieve low phase jitter performance over a wide operating temperature range. The oscillator is housed in a hermetically sealed 28-lead surface mount package. It has a unique output disable and clock through feature to facilitate on-board testing.

Top View of Package

1. By setting OD low, a test signal may be applied at CLKIN and fed through the VCO-600A to both the CLKOUT and CLKOUT to facilitate on board testing. The test signal input applied at CLKIN may be either an ECL or sinewave input (up to 1Vpp, AC coupled). CLKIN is biased internally to VBB (Vcc-1.3V) 2. An optional capacitor to ground can be placed on VBW to reduce the modulation bandwidth for narrow bandwidth phase-lock loop applications. The modulation bandwidth will be approximately 1/(12000*C)Hz, where C is equal to the capacitance in Farads. If the optional capacitor is not utilized, VBW becomes a no connect (NC) and the modulation bandwidth will be approximately equal to the nominal device frequency ÷1200. 3. By setting OD low, the outputs are disabled and CLKOUT is held Low while CLKOUT is held High. The threshold for OD is 1.4V above VEE. OD should not be driven above mid supply and during normal operation, should be left floating (use with an open collector or 3-State gate for interfacing with standard logic). If the OD feature is used during normal operation, then CLKIN should be tied through 10K? to GND to avoid any possibility of chatter on the CLKOUT outputs.

Transition times are measured from 20% to 80% of a full 10K ECL level swing. 4. The modulation bandwidth is a function of nominal center frequency and may be adjusted down through the use of an external capacitor on pin 17.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this data sheet. Exposure to absolute maximum ratings for extended periods may adversely affect device reliability.

Qualification Conformance

The VCO-600A family has undergone, and passed, the following Mil-Std qualification.

Table 5. Environmental Compliance

Parameter Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Conditions MIL-STD-883C 2002.3, TEST A MIL-STD-883C 2007.1, TEST A MIL-STD-883C 2003.5, MIL-STD-883C, 1014.7, 100% Tested MIL-STD-883C 2016Handling Precautions

Although ESD protection circuitrry has been designed into the the VCO-600A, proper precautions should be taken when handling and mounting. VI employs a human body model and a charged-device model (CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on the circuit parameters used to define the model. Although no industry wide standard has been adopted for the CDM, a standard HBM of resistance=1.5Kohms and capacitance = 100pF is widely used and therefore can be used for comparison purposes.
