Part Number: LMH1981 I am using LMH1981 to separate Sync from G_Sync and CSync signals. In Gs, it works since it has negative going Sync Pulses.
1) But if my CSync input is in CMOS or TTL level Logic (normal Pulse 0 to 2.2V). Since it doesn't have negative…
Part Number: LMH1981 Other Parts Discussed in Thread: LM1881 Hi team,
We are looking for video sync separator like LMH1981.
But only VSOUT is needed. Is there such device?
Best, Zeming
Part Number: LMH1981 Other Parts Discussed in Thread: LM1881 Hi,
We are currently working on a new project which involved and external sync device such as UltraSync One which has a SYNC output that outputs genlock or work clock.
Can we use this IC to…

Hi Team,
We have recently found a weird behaviour with the LMH1981 extractor chip.
We have PCB boards, which were manufactured two years ago, which extract correctly the FHV signals from a blackburst PAL reference.
Here is a capture…
Part Number: LMH1981 Hi Experts, I have a customer who is thinking of buying LMH1981, but wants to first confirm below: It's regarding the input signal. The data sheet says "The input accepts standard analog SD/ED/HD video signals with either bi-level or…
Part Number: LMH1981 I have a question about LMH1981.
The datasheet only shows the typical value for the HSOUT swing (tdHSOUT) at NTSC (BB) input. Please let me know the maximum and minimum values.
The output is connected to the FPGA, and I observed that…

Hello,
I'm experimenting a bit this IC, but when I'm applying a Ref Genlock source on input which generate a 1080p25 broadcast Tri-Level Sync (AJA Gen 10) on input, I only get frame line pulse on HSOUT, but nothing on VSOUT…
