Part Number: LMK61E07 Other Parts Discussed in Thread: CDCE6214-Q1 , LMK03318 , LMK03328 , USB2ANY , LMK61E2 ,
Hi,
after a long fight and experiments we have not succeeded in making LMK61Exx work in the fractional tuning mode. We would like to use it in the…
Based on your config above, it looks like... You are using LVDS instead of LVPECL, and the PLL settings are what I produced with the LMK61E2 GUI. Particularly using a different VCO frequency, fractional mode, and 1.6 mA instead of 6.4 mA. Please try this…
Hi Zhonghui,
LMK61E07 and LMK61E08 are only different in their start up EEPROM configuration. For your purposes, you need to reprogram anyway, so it's irrelevant. I was just curious if there was a thought process in choosing one over the other.
The…
Part Number: ADS1120 Other Parts Discussed in Thread: REF5025 , LMK61E07
Hi Team,
I have a question about ADS1120 internal oscillator accuracy after solder heat.
ADS1120 datasheet says internal oscillator accuracy is ±2%. this is chip level electrical…
Hi Roy,
I would recommend using the LMK61E2 profile on TICSpro.
Secondly, which device are you trying to use? Please note LMK61E07, LMK61E2, and LMK61E2-100M to name a few all use the same EVM but all have different pinouts.
Regards,Amin
Thanks Shawn.
Have you got an optimised filter setting which we can try on LMK61E07?
We found that the filter works on LMK61E2 usually sends LMK61E07 out of locked.
The LMK61xx Oscillator Programming Tool doesn't seem recognising LMK61E07 and mistakes…
Hi Amr, We do not have Synthesizers in our portfolio with integrated EEPROM/OTP. However, you could potentially evaluate a clock generator like LMK003318 or Oscillator like LMK61E07 that can output 900 MHz (Square wave - LVPECL, LVDS, CML levels).
Part Number: LMK61E2 Other Parts Discussed in Thread: LMK61E07 I've been able to shut down the LMK61E2 PLL by setting the PLL_PDN bit in DEV_CTL (R10), but haven't been able to (reliably) restore operation without a power cycle. Is there any particular…
