Part Number: LMK00105 Other Parts Discussed in Thread: LMK01801 Hi, we have some questions with LMK00105.
First, on datasheet page 16. A divider is mentioned here. Is the test block diagram like this: 100-MHz XO -> Divide-by-2 circuit -> LMK00105.…
Part Number: LMK00105 Hi there,
test condition:
1. the input is OSCin pin,
2. frequency is 52Mhz,
when the input changes from 1.8V to 1V, the noise floor of OUTPUT increases more than 10dB.
my understanding is when the input voltage decreases, the SNR…
Part Number: LMK00105 Dear Team,
According to the LMK00105SQX specification book, the actual connection method of the input terminal, the external crystal oscillator is used as the LMK00105SQX, because the input terminal has two stages of coupling capacitors…
Part Number: LMK00105 H team,
Customer has some questions. The input is single-ended. The supply voltage is 3.3V.
Related to CLKin
1. Should they take care about VCM? When the input is single-ended, what is the input voltage range?
2. According to the…
Part Number: LMK00105 Other Parts Discussed in Thread: LMK00304 Dear Team,
May I know whether you there have single end clock level shifter
from 1.8V to 3.3V
1 or 2 single end clock
Many Thanks,
Jimmy
Part Number: LMK00105 Hello E2E design support team,
The below is the waveform taken at the LMK00105 CLKin pin for existing product.
This shows that the CLKin level exceeds the specified range (0.3Vpp < Vi_se < 2Vpp) .
Waveform indicates 2.0856V…
Part Number: LMK00105 Hello, Looking at datasheet figure 6, there are two 0.1uF caps before and after 50ohms transmission line. My customer thinks either one is good enough for ac coupling. Any specific reasons to recommend two caps for ac coupling? …
Part Number: LMK00304 Other Parts Discussed in Thread: LMK00105 , LMK04832 Hello team,
I have a question about LMK00304 and LMK00105. Could you answer below two cases?
Regarding OSCin and CLKOUT of LMK00304 and LMK00105, What will be output on CLKOUT if…
Part Number: LMK00105 Input to LMK00105 is a 1Hz single ended signal with 50% duty cycle.
The preferred config (Figure 6 in datasheet) is used in our design.
At the output, a 17usec pulse is observed with ringing seen on the negative edge of the pulse…
