*T_A= 0 - 70°C; V_DD= 3.3 V +/-5%; C_L=2pF, R_S=33.2 , R_P=49.9 , I_REF= 475

¹Guaranteed by design and characterization, not 100% tested in production.

²All Long Term Accuracy and Clock Period specifications are guaranteed assuming that 25MHz_x is tuned to exactly 25.000MHz

Ω

I_REF= V_DD/(3xR_R). For R_R= 475 (1%), I_REF= 2.32mA. I_OH= 6 x I_REFand V_OH= 0.7V @ Z_O=50 .

⁴Rise/fall time measured on single-ended waveform per CK410 specification.

⁵Slew rate measured on differential waveform per CK505 specification.
