Part Number: LMH1981 Tool/software: Hi all,
My customer wants to detect 1080/60P using LMH1981. Does this device support 1080/60P detection?
My customer actually put three patterns of 1080/60P, 1080/59.94P, and 1080/50P into LMH1981. It seems to be…

We currently use LMH1981 + LMH1983 to achieve the 3G GenLock solution. However, LMH1983 supports a maximum clock output of 148.5 MHz, which cannot…
Part Number: LMH1981 Tool/software: Hello E2E Experts,
Good day.
Can this chip use dual voltage operation ?? Do pins Vcc-1, Vcc-2 and Vcc-3 need to be at same voltage? I would like to use Vcc-1 and Vcc-2 at 5V and then use the output Vcc-3 at 3.3V…
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…

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…
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…
