TL2844: As for TL2844DR-8 Datasheet Update

shimamura.tomoyuki

Part Number: TL2844

Tool/software:

Hello Team

Could you please confirm if there are any differences in the "Oscillator frequency" section (Section 5.5) of the TL2844DR-8 datasheet between Rev.I and Rev.J? I do not have Rev.I on hand to verify.

A customer has pointed out differences in the graph (Figure 5-10. Timing Resistance vs Frequency) between Rev.I and Rev.J.

While there may be differences in the typical values shown in the graph, is it correct to understand that the specifications still fall within the Min/Max values stated in Section 5.5?

Best Regard,

Tomoyuki Shimamura

Thank you for providing the information on the old and new datasheets. We have confirmed that the specifications (Min/Typ/Max) for the Oscillator frequency in section 5.5 [Oscillator Section] have not changed between the old and new datasheets.

We understand that the difference in the Graph (Figure 5-10. Timing Resistance vs Frequency) between Rev.I and Rev.J is due to the Rev.J graph being measured with RFAB products, which have slightly different characteristics compared to SFAB. Is our understanding correct that both graphs (Figure 5-10. Timing Resistance vs Frequency) in Rev.I and Rev.J fall within the specified (Min/Max) range?
