LMH0397: Reclocker Lock Indicator

Part Number: LMH0397

Hi,

I understand that by default, LOCK_N is the reclocker lock indicator, and this pin asserts low when the LMH0397 achieves lock to a valid SMPTE data rate.
So, could you please tell me the detailed conditions when LOCK_N is asserted to low? Additionally, video data may be output even if LOCK_N is de-asserted to high.

Best regards,
Kato
