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…

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…
Noel-san, Timothy-san,
Thank you for reply.
> I wanted to see if this issue was still present? Yes,,, I'd like to clarify the reason.
> do you have the understanding that TOF is aligned Yes, I think TOF is aligned, because LMH1983 register ALIGN STATUS…
Part Number: LMH1983 Hi team,
I got a question from customer.
I am using the LMH1983 in a product design. In this application we are only using the HIN reference input. VIN and FIN are both tied low. The HIN reference is a 10MHz clock. We are setting…
Part Number: LMH1983 Hello Expert, My customer is considering LMH1983. We think 0x1C(Loss of Lock Threshold) and 0x2D(Lock Step Size) is the setting of judging whether PLL is locked. In their evaluation, then they used 0x1C and 0x2D register as default setting…
