LTC2183 CLKOUT timing afer first ENC input

Hello

I am FAE in Japanease distributor.

Our customer uses LTC2183 with ENC=80MHz, SCK=2MHz.

They writes data 02h to address 03h  for reset  by SPI after power on.

Then they writes data 02h to address 03h for CMOS DDR mode setting by SPI .

CLKOUT signal starts to output 1us after ENC signal inputs.

Is this 1us a normal time?

Why is this time needed? (DLL or PLL locktime?)

Our customer confirmes address 01h data 00h and address 03h data 02h.

Best regards

N.Kokubo
