Part Number: LMH1980 Other Parts Discussed in Thread: LMH1981 , LM1881 Hello,
What is the main difference between LMH1980 and LMH1981 function wise and electrical wise? From my understanding, the customer can utilize these two parts for video genlock purpose…
Part Number: LMH1980 Dear sir, I am using LMH1980 as a SYNC separator to separate the HSYNC , VSYNC from green video of VGA(composite SYNC has been inserted in green video of VGA).But un expected HSYNC pulses are observed at output of LMH1980. Due to this…
Other Parts Discussed in Thread: LMH1980 Hi sir,
May I know LMH1980 suitable this case when connect CVBS signal (Composite video) use capture frame rate to do trigger signal ? Input rang 5V ~ 12V
Other Parts Discussed in Thread: LMH1980 Good day,
I am using the LMH1980 in a design which requires the input to survive a 50V 5 ms surge.
Does the AC coupling through a 100nF capacitor as per the reference design provide sufficient surge reduction to…
Other Parts Discussed in Thread: LMH1980 Hi All, We are using this chip in a design for a sync interface unit and have picked up a problem that we have also reproduced on the LMH1980 EVAL board.
Input sync pulse are delayed about 700ns on the falling…

Other Parts Discussed in Thread: LMH1980 Good Day
We are using the LMH1980 in a sync interface unit design and notice that with no sync input random output pulses are at times output from the device. With a normal PAL input the device works as expected…
Other Parts Discussed in Thread: LMH1980 Hello Team,
Please allow me to confirm the slice level for LMH1980.
I am understanding the slice level is +70mV above V_sync clamp level.
Is this +70mV threshold applied to tri-level sync, too ?
Best Regards,
K…
Other Parts Discussed in Thread: LMH1980 Hi Team,
The rise time of tri-level sync signal for 1080i is normally f=0.054us. The datasheet defines t_HSOUT as 525ns(TYP).
However, our customer would have a tri-level sync signal with very steep rise time f…
