Free Run.
Internal to the device, route XA/XB to CKIN2. This allows the device to lock to its external
reference.
0: Disable Free Run
1: Enable
CKOUT Always On.
This will bypass the SQ_ICAL function. Output will be available even if SQ_ICAL is on
and ICAL is not complete or successful. See Table 4.
0: Squelch output until part is calibrated (ICAL).
1: Provide an output. Note: The frequency may be significantly off until the part is
calibrated.
Reserved.
CK_CONFIG_REG.
This bit controls the input clock configuration for either normal CLKIN function or FSYNC
operation. Whenever CK_CONFIG_REG = 1, FSYNC_ALIGN_MODE must not be set to
1.
0: CKIN_1, 2, 3, 4 inputs do not have a synchronized relationship. CLKOUT5 is an inde-
pendent output. There is no FSYNCOUT.
1: CKIN_1, 3 and CKIN_2, 4 Clock/FSYNC pairs. CKOUT5 is configured as the FSYNC
output.
Reserved.
Bypass Register.
This bit enables or disables the PLL bypass mode. Use is only valid when the part is in
digital hold or before the first ICAL.
0: Normal operation
1: Bypass mode. Selected input clock is connected to CKOUT buffers, bypassing PLL.
