difference between clock delay and clock latency

Hi guys,

would you tell me the difference between clock delay and clock latency??

Thanks

Hi,

Out of curiosity I did an internet search.

The first hit gives:

Clock Latency is the general term for the delay that the clock signal takes between any two points. It can be from source (PLL) to the sink pin (Clock Pin) of registers or between any two intermediate points. Note that it is a general term and you need to know the context before making any guess about what is exactly meant when someone mentions clock latency.

Clock delay generally delay in time from source edge to target, due to gate delay, RLC effects in
signal path.....0

Latency can also be time for clock oscillator to start up.....

Latency usually means delay in clock cycles. For example, if the output of a circuit changes 3 clock cycles after the input that would be a clock latency of 3 cycles.
