Differential swing (amplitude) control for
unlocked signals output on DDO1 (when
reclocker is operating in BYPASS mode). For
3_h details refer to Section 4.5.3.
Also applies when the device is not locked.
Takes precedence over rate-specific swing
controls
Differential static amplitude control for
DDO1 when the output is muted. For details
3_h refer to Section 4.5.3.
Takes precedence over rate-specific swing
controls and bypass swing control
Differential swing (amplitude) control for
3_h 5.94Gb/s (6G UHD-SDI) signals output on
DDO1. For details refer to Section 4.5.3.
Differential swing (amplitude) control for
3_h 2.97Gb/s (3Gb/s SDI) signals output on
DDO1. For details refer to Section 4.5.3.
0_h Reserved. Do not change.
Used to manually bypass the retiming block
in the reclocker.
0_b: Retimer not bypassed
0_h 1_b: Retimer bypassed
The assertion of MANUAL_BYPASS takes
precedence irrespective of the setting of
AUTO_BYPASS
Selects between automatic and manual
bypass of the retiming block when the
reclocker is not locked.
1_h
0_b: Auto-Bypass is disabled
1_b: Auto-Bypass is enabled
Even if AUTO_BYPASS is asserted, the
assertion of MANUAL_BYPASS will still cause
the retimer to be bypassed.
1_h Reserved. Do not change.
Selects sampling method for LOCK
DETECTION
0_{h 0b: Strict sampling}
1_b: High-jitter sampling
2_h Reserved. Do not change.
