Part Number: LMK00804B Tool/software: Hi,
We are using clock buffer LMK00804BPW in our circuit, The query is regarding VDD supply support for the 1.8V.
In date sheet Absolute maximum rating its given as it can take -0.3 to 3.6V as attached. Clock sel…
Part Number: LMK00804B Hi Team,
Please Provide the Clarification for the part LMK00804BPW
a. There are two values provided for Junction temperature as Tj= 125C and Tj = 150C, which one to consider?
b. What is the Bond wire? Ist copper or gold? If the…
Hello Conor,
Conor said: My question, as stated in my first post, is about the timing of VOUT switching relative to VIN. In the capture in my first post, Vout switches from LOW to HIGH when VIN is about 0.4V, and from HIGH to LOW when Vin is about 2.9V…
Part Number: LMK00804B-Q1 Other Parts Discussed in Thread: LMK00804B Hello,
1. Customer is requesting if it's possible to use a 1.8V Clock input with this device.
2. They would also like to "Daisy Chain" first LMK00804B output to second …
Hello Arshad,
Arshad Mughal said: 1. Can I directly connect the TCXO (LVCMOS) output with an output impedance of 200 ohm to LMK00804B LVCMOS_CLK input (pin 8) as shown below? Considering driver and transmission line impedance will be different?
That should…
Part Number: LMK00804B Other Parts Discussed in Thread: LMK00804 Hello Team,
below picture represents a 50 Ohm load termination to VDDO/2, correct?
So I calculate current = VOH/93Ω = 2.6V/93Ω = 28mA. Doesn't this violate the IDDO Power Supply…
Part Number: LMK00804B-Q1 hello,
my circuit design as below for your reference; now the VDDO is 1v8, the Q2 connect with FPGA I/O via two resistors dividing voltage (because the FPGA I/O input voltage scope is 1V-1.8V) ,I want to keep the FPGA input voltage…
Part Number: LMK00804B hello sir.
You want to enter it into LVCMOS_CLK of LMK00804B using 40MHz TCXO. For VDD and VDDO on the LMK, enter 3.3V. My TCXO output range is 0.8Vp_p. If you look at the datasheet, the VIL of LMK00804B is max 1.3V and VIH is min…

Hello Abhed Misra,
Do we really need the second LMK00804B?
Besides the 40MHz, LMK00804B is also used for Sync. But the Sync frequency is really low.
Could we use low-cost circuit…
