Part Number: LMH1980 Hi team
My customers want to apply the LM1881 as an ISL59885 replacement.
What should be important when reviewing?
Is there any problem to replace it immediately?
Thank you
Part Number: LMH1981 Other Parts Discussed in Thread: LM1881 , , LMH1980 Good day,
I am curious if the LMH1981 is able to strip Hsync and Vsync from a 15Khz composite video input signal (i.e. 240p)? The former LM1881 was able to and it doesn't appear it…
Hi Simon,
Thanks for your answer. I was comparing the datasheets between the two devices, and it seems that the LMH1981 has improved jitter performance on the HSync signal. It's mentioned repeatedly in the datasheet, while not in the LMH1980 datasheet…
Other Parts Discussed in Thread: LMH1251 , LM1881 if config the 3 dac as YPbPr, just use LMH1251.
if config as RGB ,just use LM1881.
is it easy? have fun!

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
I was using the LM1881N to receive SD composite video and output vertical sync pulse to my equipment.
The equipment needs the vertical sync to function.
I'm switching to a HD video camera which has no composite output.
The new camera has a veritical…
LMH1981 and LMH1980 are two video sync separator with automatic format detection that can support all frame rates of 480i/p, 576i/p, 720p, 1080i/p video standards. These parts are from National Semiconductor's video timing portfolio.
LMH1981 has 50…
