Part Number: LMH1981 Hi Team,
My customer would like to understand "VIN v/s VS Signal's jitter and delay time" specifications. Is there any data about this?
Regards,

Part Number: LMH1981 Hi,
My customer would like to use LMH1981 as GENLOCK circuit. In this case, This circuit don't need cable equlizer? D/S Figure 2. mentioned no cable equlizer test circuit.

Part Number: LMH1981 Should we use 75 ohm single-ended impedance trace for signal routing to Vin?
If it is yes, where should we use 75 ohm impedance trace?
Is it from BNC to external 75 ohm termination resistor point? or from BNC to Vin pin?
Best Regards…
Part Number: LMH1981 Hi support team!
We are using the LMH1981 to extract the vertical sync from a bi- or tri-level genlock.
Now we need to process 3G video with the respective genlock inputs, that is 1080p/50 , 1080p/59.94. According to the datasheet…
Part Number: LMH1981 Hi, Team,
What is the maximum current value that can flow out from the output terminal?
If 1 KΩ terminating resistor is added to the HSOUT output of the pin, current of 3.3 mA (when VCC = 3.3 V) flows, is there no problem? The…
Part Number: LMH1981 I am preparing a termal simulation of an electronic board where LMH1981MT/NOPB sync extractor will be located. The datasheet only gives information on the junction-to-ambient resistance, but we require also the junction-to-case and…
Part Number: LMH1981 Other Parts Discussed in Thread: LMH1982 , , LMH1983 , LMK05028 Hi team,
My customer wants to use the device LMH1981+LMH1982 to achieve the Genlock function.
Requirements below:
1.equipment A and equipment B Stitching synchronization to…
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…
Part Number: LMH1981 Hello team,
Hope you are doing well. Please see below customer question:
We are using the TI Sync Separator LMH1981MTX/NOPB along with a low jitter DSPLL device from a clock synthesizer/jitter cleaner. This is our circuitry for receiving…
