Thanks for the information.
As I´m using the HMC1033 only as VCO, this question came along.
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…
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…
Thank you for the tips. I use the 10MHz reference from the spectrum analyzer. When measured by the spectrum analyzer itself, no spurs are visible. Not sure, if this can be considered as a proof of spur-free source. I assembled another board without the…
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 …
Both HMC830 and HMC832 will meet these requirements but the application must utilize a tunable reference and manual tuning to meet the -60dBc spurious and hop time requirements. I've attached an appnote on manual tuning. With a fixed 50MHz reference Figure…
I'm working with the PLL VCO HMC830.
I want to use a look-up table (LUT) for manual calibration, as decribe in "Frequency Hopping with Hittite PLLVCOs Application Note" (attached) (https : // www . hittite.com/content/documents/application_notes…
HMC829, HMC830, HMC832, HMC832A, HMC833, HMC834, HMC835, HMC983/984, HMC1033, HMC1034
The above HMC PLL+VCO Eval board offers the user flexible reference signal sources.
