Part Number: LMK61E2-125M Other Parts Discussed in Thread: LMK61E2 Dear Colleague, We tried to change the default clock frequency to 200Mhz by writing to EEPROM of LMK61E2BBA (default frequency on 125Mhz). But, after the power cycle, I2C communication…
Part Number: LMK61E2-125M Other Parts Discussed in Thread: LMK61E2 Hi Timothy,
Thanks for your advice. But unfortunately, we could not detect the LMK61 device after looking through all the i2c addresses.
Then, recently we experiment with another device…
Part Number: LMK61E2-125M Other Parts Discussed in Thread: CDCLVP1102 , LMK61E2 Per the OSC data sheet, the LVPECL Vout, Diff PP is 2xVod = 2x1200mv max= 2.4Vpp. The input of the buffer CDCLVP1102rgtt LVPECL is Vin Diff pp 1.5V max, per it's data sheet…
Part Number: LMK61E2-125M Other Parts Discussed in Thread: LMK61E2 Hi,
The LMK61E2 is supplied with 3.3V. It will be programmed from Xilinx Kintex 7 FPGA that operate at 1.8V logic.
So SCL and SDA is pulled up using 4.7K resistors to meet I2C standards…
Hi Dean and thanks for your msg,
I think i have finally concluded which parts to use. I am focusing on clock oscillator LMK61E2-125M designed for 125MHz and the 4-LVPECL-output clock buffer CDCLVP1204.
This started with me knowning almost nothing about…
Part Number: LMX2571 Other Parts Discussed in Thread: LMK61E2 , ADS4225 Hi,
I am a bit confused regarding the PLL LMX2571 output jitter.
I have chosen the clock LMK61E2 and considering the PLL LMX2571.
The PLL output will be driven to the ADC ADS4225 which…
Part Number: ADS4225 Other Parts Discussed in Thread: LMK61E2 , LMX2571 Hi,
I am building a scope with the ADS 4225 and based on the fact that the max sampling rate is not 1GS/s but 125MS/s i was searching for a way to take full advantage of its' 550MHz…
