Part Number: LMK01801 Hi,
In my application, input = 1GHz sine wave signal with -150dBc/Hz phase noise @100k offset. I like to introduce a frequency divider then output a 100MHz signal with better than -165dBc/Hz phase noise @ 100k ofs. I looked into…
Part Number: LMK01801 Hello,
My customer has a question. The datasheet expalins how to deal with unused clock output pins like the below.
It recommends "powered down". But im my customer's case, they uses CLKout0~2 and CLKout4~6. Only CLKout3 and…
Part Number: LMK01801 Hello, My customer is going to use LMK01801 with the below configuration. CLKin0=100MHz CG1: CLKout0~2=100MHz CG2: CLKout4~6=50MHz (Div 2)
They they would like to know skew between CG1(CH0~2) and CG2(CH4~6). I found some E2E posts…
Part Number: LMK01801 Tool/software: Hello,
I am trying to program LMK01801 (testing on LM01801BEVAL) to generate CLKout12 of 250 MHz and CLKout10 of 125 MHz with 500 MHz input clock. I am bypassing input divider and configuring CG3 divider to 4 and…
Part Number: LMK01801 Other Parts Discussed in Thread: LMK05318 , , LMX2595 Tool/software: Hello,
Our reference clock source is a sine wave OCXO at 100MHz. We need to generate 100MHz LVDS and 100MHz LVCMOS and 10MHz LVCMOS from this.
Please advise…
Part Number: LMK01801 Hi,
In the dual clock divider buffer(LMK01801) after powering up the BANK A which is pin 6(Vcc1_CLKout 0_1_2_3) and pin 20(Vcc3_CLKout 4_5_6_7) starts to consume 1.72A and the power supply voltage 3.3V dips into 2.8V without any…
Part Number: LMK01801 Hi,
We are using LMK01801 in our design. We are using Pin Control Mode (EN_PIN_CTRL = High) as per LMK01801 datasheet. We are not getting any output from LMK01801, kindly help any changes required in attached Schematics.
We are…
Part Number: LMK01801 Hello Sir,
I'm Using LMK01801, out of these dividers CG1 to CG4, CG2 only working in my board, I've set all Clocks in LVDS mode, Please help us.
Thanks & Regards,
Venkatesh
Part Number: LMK01801 We are experiencing issues programming the LMK01801 and require clarification on information from the datasheet.
In section 9.5.1, "Registers are programmed in numeric order with R0 being the first and R15 being the last register…
Part Number: LMK01801 I use the LMK01801 in several designs with Pin Control mode configured.
In one of the designs, I used the LMK01801 with a 1GHz clock at CLKin0 input and set the CLKout0-7 to LVDS clocks div by 1 (CLKoutTYPE_0 and CLKoutDIV_0 and…
