Part Number: LMX1214 Other Parts Discussed in Thread: LMX1204 , LMX1205 , Tool/software: Hello,
The data sheet for the LMX1214 and related devices such as LMX1204, LMX1205 all list a minimum operating frequency of 300MHz.
We have an application where…
Part Number: LMX1214 Tool/software: Hi,
I am using 100nF 0402B104K160CT decoupling cap for clock buffer voltage pins.
Is this part, ok? or is any special type of Wideband capacitor required?
Please share details on the same.
Part Number: LMX1214 Tool/software: Hi,
I am routing the CLKOUT1 output of LMX1214 to FPGA. I have the termination circuit to match the common mode voltage at FPGA end.
Should this clock be routed as 100 ohm differential in this case?
Thank…
Part Number: LMX1214 Tool/software: Hi,
The input frequency to clock buffer is 1800MHz and we plan to connect CLKOUT pins to FPGA and set them at output frequency of 225MHz.
The CLKOUT pins seem to be similar to CML standard. FPGA can support LVDS…
Part Number: LMX1214 Tool/software: Hi,
I have a differential 225MHz clkout to FPGA. LVDS Input side AC-coupling requirement in FPGA is highlighted.
What is the power out dBm need to choose for clkout to meet the FPGA input voltage requirement?…
Part Number: LMX1214 Tool/software: Hi,
We have an implementation as below and a requirement to have a common clock source for both ADC sampling clock and FPGA.
Since FPGA cannot take 900MHz input (from CH-B of PLL or CLKOUTS2-4 of ClkBuffer), we…
Part Number: LMX1214 Tool/software: Hi,
We have the below implementation of SPI bus from FPGA to the Clockbuffer thru' an optocoupler.
What should be the voltage reference for these SPI signals at clock buffer side - VPINM_2V5 or CB_VCC23_2V5?
Please…
Part Number: LMX1214 Tool/software: Hi,
We want to interface the FPGA LVDS output to the SYNC pin. Based on below FPGA LVDS output spec, both common mode and differential seem to be out of spec.
For FPGA outputs from 1V to 1.425V. VCM of SYNC pin…
Part Number: LMX1214 Other Parts Discussed in Thread: LMX2582 Tool/software: Hi,
can you share information for below points.
1. What is the value on jitter I/P pins (CLKIN_P/N).
2. What is the value on jitter O/P pins (CLKOUT1_P/N).
3. What is…
Part Number: LMX1214 Tool/software: HI,
We have a query with LMX1214 Current consumption.
For our application, only one Clock output and our power setting is 4. I have attached my current calculations FYR.
On calculating we are getting 285 mA…
