Part Number: LMK00308 Other Parts Discussed in Thread: LMK00304 ,
Hi All,
I am sending this email to ask some questions on input bias voltage and termination resistor of LMK00304/08.
My customer has applied LMK00304 and LMK00308 to new system and they…
Part Number: LMK00308
Hi,
we need a clock buffer/mux which is able to multiplex two input and fan out 8 output . One of the input signals is LVDS(0-1000MHz), the other is analog sine-wave(0-100MHz). The output signal should be LVDS. LMK00308 looks nice…
Hi Alen,
Thank you for your patience.
After some considerations of power and optimization. I think using 2 LMK0482x is not great solution. It would be power hungry and there would be issues with correct synchronization across multiple devices/FPGA.
I…
Part Number: LMK00308 Other Parts Discussed in Thread: LMK00101 Hi,
We are using lmk00308 & lmk00101 in our design ,
1. out of the 3 clock inputs for both the IC's, we are using clkin0 only , can we leave the unused inputs clkin1 & OSCIN floating…
Part Number: LMX2581 Other Parts Discussed in Thread: LMK00308 Hi,
I would like to drive lmx2581 using lmk00308. Is it good to add clock buffer to convert differential to single ended or using reference design from EVM ?
If second option is preferred…
Hi,
lmk00308 output is converted to single ended using the reference circuit given snau136c.
But for lvds outputs of lmk00308 VOD = 400mv & vos=1.25V , will this be sufficient to drive OSCIn of lmx2581 which requires an AC coupled input of min …
Part Number: LMK00308 Other Parts Discussed in Thread: LMK61E2
Hi,
We would like to use si570 to drive LMK00308 with LVDS (Vcm=1.20V) signal and we want to use as few components as possible due to space limit which means DC coupling, direct connection…
Part Number: LMK00308 Hi,
1.Can I operate CMOS control inputs such as CLKin_SEL1 or CLKin_SEL0 or CLKoutA_TYPE0 of multiple (say 5 numbers) LMK00308SQ from a single 3.3V LVCMOS GPIO pin of KINTEX7 FPGA without any loading effect ?
2.What to do with unused…
Part Number: LMK04610 Other Parts Discussed in Thread: LMK00308 ,
Hi,
A 100MHz LVDS (4-mA HSDS or 6-mA HSDS) clock is generated from LMK04610 and is fed as input to the LMK00308. The differential output voltage swing is much higher than the normal LVDS…
Part Number: LMK00308 Other Parts Discussed in Thread: , LMK00306EVM , LMK00306 Hello,
I have a question about LMK00308.
[Background #1]
The LVDS interface circuit with AC coupling to receiver with internal 100 ohm termination is listed in the datasheet…
