• RE: ADF4110 Channel Spacing

    Hello ,

    I will send you on a reference circuit using the ADCMP553 later today/tomorrow....looking at the circuit, the o/p stage will be similar to the ADCLK905 reference circuit that I sent you ( using a single 3.3Volts supply voltage). The input will…

  • RE: RE: Help with ADCMP553

    Hi Vamsee_27,

    You should set a reference voltage at the inverting input. this voltage should be in the area of your input swing, if you what a 50% duty cycle you can set the reference voltage to 750mV, please be reminded though that input offset voltage…

  • LT Spice Model for ADCMP553 Conmparator

    Hi All

    I am looking for LTspice model file for ADCMP553 comparator. Does any one have it.

    Thanks

  • RE: Use ADF4158 with frequency below 0.5 GHz

    Hi Vlad,

    ADCMP604/ADCMP605 should also be fine. However, they are a bit slower (rise/fall time, propagation delay)  and have narrower input bandwidth compared to the ADCMP553. What's more, the CFTL(Circuit from the lab) will contain the ADF4153 and ADCMP553…

  • ADCMP553中VCCO-2.0V的问题

    最近在做一个电路,其中一部分采用了ADCMP553比较器,第一次接触LVPECL电平,看数据手册上写着在输出端需要加一个VCCO-2.0V的电平,但是553不同于551和552,其并没有VCCO引脚,那么这里的VCCO是和它的VCC相等都为3.3V嘛?那么是不是说在输出端上各加一个1.3V的电平就ok了。

    于是我用ADP1711-1.3产生了一个1.3V的电平通过一个50欧姆的电阻加在了553的输出上,测试时发现1711的输出电平变成了2.6V,后来发现这个2.6V和未加输入和参考时的553的输出电平相等…

  • Use ADF4360-9 to track an incoming carrier signal around 150MHz

    I am trying to track an incoming carrier signal around 150MHz for an indoor application. The carrier frequency is one of 50 random channels with a frequency hopping pattern. Most of reference designs with PFD and PLL are for clock generations with a preset…

  • RE: Limitations of LT1721

    In the first page of LT1721 show clear that delay is 4.5ns. So, it is not suitable for your application.

    If you only want to test the wave form (because you don't mention to rise/fall time & duty), you can you ADI higher speed comparator to generate…
