Part Number: LMH1983 Other Parts Discussed in Thread: LMH1981 Noel-san,
Sorry to be stikky, but please allow me to confirm bellow.
The skew among (H,V,F)IN from LMH1981 to LMH1983 through FPGA is expected to be about 2.0 ns.
Above condition, will the…
Part Number: LMH1983 Are ferrite beads required on VDD_PLLx and VDD_CLKoutx? EVM has ferrite beads on L6-L11, while datasheet Figure 32 on pg43 does not show any.

Part Number: LMH1983 Hi all Would you mind if we ask LMH1983? There is the description of Loop Band(BW) on the datasheet.
On the calculation(the datasheet P13), BWPLL1 is as the following; BW PLL1 = Rs x Kvco x Icp1 / (2*π*FB_DIV) So, on the calculation…
Part Number: LMH1983 Other Parts Discussed in Thread: LMH1982 , Hi
I want to use the part in GENLOCK mode .
My system provides H sync and V sync only to my circuit .
Can I ignore the Fin signal (as LMH1982) and use only the H V sync?
My inputs to the FPGA…
Part Number: LMH1983 Noel-san, Timothy-san,
In the last thread, you mentioned that preparations will take until the end of May. Please tell me about the current status. BR, Sohhei

Dear TI Circuit Engineer
Hello, I am a researcher working as a circuit engineer at LG Electronics.
I made a circuit with LMH1983 and LMH1981 and FPGA ICs, and I would like to…
Part Number: LMH1983 Hi team,
Just to confirm, is there no other difference between LMH1983SQ/NOPB, LMH1983SQ E/NOPB, and LMH1983SQ X/NOPB except for reel quantity?
Best regards,
Hayashi
Part Number: LMH1983 Hello,
I am using the LMH1983SQE chip on one of our product. I am not able to detect the device on the I2C bus. I tried changing the to various address of the IC to 0x67, 0x66 and 0x65 using the ADDR pin on the IC, but still I was…
