Hello, I am currently working on a project where we are using an HMC1033 N-PLL to turn an input 10MHz clock signal into an output 125MHz differential clock signal. We have designed a PCB ourselves to use with the HMC1033, and verified its connections…
Hello,
is there a minimal configuration available for the HMC1033? I'm designing a testbed for a board containing this IC and fine tuning will be done later by different people. For simple liveness test I'd link to have a simple configuration that takes…
HMC1033寄存器数据按照芯片手册及 Hittite Pll 评估软件中寄存器的值。
spi已经测试可用。
HMC1033的测试CP脚可控。
但是输出一直是36M。
更改整数分数寄存器输出仍不变。
I configuration my hmc1033 board with the procedure,generation 500MHz clock:
HMC1033_Write(0x0A,0x2006); //reg A HMC1033_Write(0x08,0xC1BEfF);//reg8 HMC1033_Write(0x0F,0x81); //reg f HMC1033_Write(0x07,0x14d); // reg7
HMC1033_Write(0x0B,0xF8061);//reg…
I didn´t found the information of the Vtune Voltage Range in the datasheet of the HMC1033.
I suppose it´s 0-3.3V but I wanted to be sure.
Thanks in advance!
I would like to know if the PLL HMC1033 could be used with LT5512 Mixer.
What is the output impedance of HMC1033 and how is the matching circuit with LT5512. Should I go for differential or single-ended I/O ?
Thanks in advance,
XL
Dear Sirs,
according to https://www.hittite.com/content/documents/operating_guide/pll_operating_guide_rf_vcos.pdf there shall be no spurious at frequencies other than multiples of PD frequency in Integer Operation. Unfortunately, that is not my case…
自己做了hmc1033的PCB板,用来产生500MHZ的时钟信号,写寄存器的代码如下:
HMC1033_Write(0x0A,0x2006); //reg AHMC1033_Write(0x08,0xC1BEfF);//reg8HMC1033_Write(0x0F,0x81); //reg fHMC1033_Write(0x07,0x14d); // reg7
HMC1033_Write(0x0B,0xF8061);//reg bHMC1033_Write(0x0C,0x0); //reg …
雷达广泛用于民用应用,从执法部门实施的汽车系统和速度监控到空中交通管制、天气和海上监控。雷达发射无线电波,然后通过其路径中的物体反射。雷达接收机处理这些反射波以确定物体的范围、角度或速度。例如,海上雷达可测量船舶方位和距离以防碰撞并进行船舶导航。在港口或海湾处,船舶交通服务雷达系统用于监控和调节繁忙水域中的船舶运动。配合飞机应答机系统一起使用的类似民用空中交通管制雷达确定相似特性,以确保飞机之间保持安全距离并协调飞行路径。
