•
Refresh Adapt Type
: Select either
Fine
or
Coarse
.
For Fine, the duration of the Refresh ADAPT sequence is calculated as
T
ADAPT
= 650 * (ADAPT_ 1).
For Coarse, T
ADAPT
= 650 * 2
ADAPT_length
, where ADAPT_length < 18.
Low Speed Timing Settings
•
LS Prepare Length [SI]
: This defines the number of DIFP states before
the PWM burst starts. The actual
PWM Prepare Length
can be
calculated with the formulas given in
Table 7 “PREPARE, SYNC, and
ADAPT Attribute and Dependent Parameter Values” of the MIPI
®
Alliance Specification for M-PHY
®
Version 5.0document
.
•
PWM Sync Length [SI]
: This defines the number of SYNC pattern
symbols before the burst starts in PWM mode. It can be selected from 0
to 15, but for the PWM gear available in this version of the Frame
Generator, the SYNC sequence is not added, that is, PWM Sync Length
is 0.
The Sync Length can be calculated using the method given in T
able 7
“PREPARE, SYNC, and ADAPT Attribute and Dependent Parameter
Values” of the MIPI
®
Alliance Specification for M-PHY
®
Version 5.0
document
.
•
PWM Sync Range
: Select either
Fine
or
Coarse
for the PWM Sync
Range.
For Fine, the duration of the HS sync sequence T
SYNC
is equal to the HS
Sync Length: T
SYNC
= SYNC_length.
For Coarse, T
SYNC
= min(2
SYNC_length
, 2
14
).
For more details see T
able 7 “PREPARE, SYNC, and ADAPT Attribute
and Dependent Parameter Values” of the MIPI
®
Alliance Specification
for M-PHY

Version 5.0 document and the text just before that table
.
•
Tail of Burst [UI]
: This is defined as the transmission of a series of either
0s or 1s after the last 8b10b symbol of the burst.
•
Sleep Length [UI]
: Sleep is the power-saving state in the LS mode. It
will add as many DIFN (0) states as given by the Sleep Length in unit
intervals. For a PWM burst, LS Sleep adds all PWM zeros and one PWM
one. Example: The LS Sleep of PWM (10) will be nine PWM zeros and
one PWM one.
Other Timing Settings
•
Squelch Pulses
: This defines the number of pulses in the squelch data
block. This parameter only affects the data output when the sequence
file contains a “SQUELCH” entry in the data block definition (see
•
Squelch Pulse Width
: This is the width of the DIFN pulse in the
squelch data block.
