TCLK is a test clock driven in on the XTALIN input in test mode.
“
Normal
”
mode of operation
Range of reference frequency allowed is min. = 14.316, nom. = 14.31818 MHz, max. = 14.32 MHz.
Frequency accuracy of 48 MHz must be +167PPM to match USB default.
Mid. is defined a Voltage level between 1.0V and 1.8V for three-level input functionality. Low is below 0.8V. High is above 2.0V.
Required for DC output impedance verification.
These modes are to use the SAME internal dividers as the CPU = 200 MHz mode. The only change is to slow down the internal VCO to allow under clock
margining.
