Other Parts Discussed in Thread: DS90CR216

Hi,

There is no description of the maximum values of RSRC / RHRC of data sheet.

www.ti.com/.../ds90cr216.pdf

①What is the maximum value of RxOUT Setup / Hold time at f = 40MHz?

②What is the maximum value at f=25MHz?（as a reference）

Best regards,
Seishin

    Hi Seishin-san,

    1. This parameter is not characterized. There is no maximum value for RxOUT Setup/Hold time for f = 40 MHz, as the critical parameter is only the minimum. By knowing the minimum setup and hold time, the designer will be able to determine whether the timing margin for the receiver's outputs are compatible with the timing requirements of the endpoint display that the DS90CR216 outputs will interface with.

    2. The minimum value of the RxOUT Setup/Hold time will be larger than at f = 40 MHz. However, this value is not characterized, and please note that the critical parameter we would characterize would still only be the minimum, not the maximum.

    Regards,

    Michael
