LMH1983: H-Sync Input question

Jeff Larsen

Part Number: LMH1983

In my application I only care about the clock outputs and do not use the TOF outputs. Can I drive the H-sync only with a generated H sync equivalent to NTSC (525i) and set V-sync and F-sync to 0 ?

Hi Jeff,

Only Hin signal is needed to lock the PLL. Vin (and Fin for interlace video input) is only needed to align the output TOF pulses.

Thanks and regards,

Amin
