Description
RED Parallel Interface Data Output Pins (MSB = 7, LSB = 0)
In power-down (PDB = 0), outputs are controlled by the OSS_SEL (See
pins are inputs during power-up (See STRAP Inputs).
GREEN Parallel Interface Data Output Pins (MSB = 7, LSB = 0)
In power-down (PDB = 0), outputs are controlled by the OSS_SEL (See
pins are inputs during power-up (See STRAP Inputs).
BLUE Parallel Interface Data Output Pins (MSB = 7, LSB = 0)
In power-down (PDB = 0), outputs are controlled by the OSS_SEL (See
pins are inputs during power-up (See STRAP Inputs).
In power-down (PDB = 0), output is controlled by the OSS_SEL pin (See
control signal pulse width must be 3 PCLKs or longer to be transmitted when the Control
Signal Filter is enabled (CONFIG[1:0] = 01). There is no restriction on the minimum transition
pulse when the Control Signal Filter is disabled (CONFIG[1:0] = 00). The signal is limited to
2 transitions per 130 PCLKs.
In power-down (PDB = 0), output is controlled by the OSS_SEL pin (See
control signal is limited to 1 transition per 130 PCLKs. Thus, the minimum pulse width is 130
PCLKs.
In power-down (PDB = 0), output is controlled by the OSS_SEL pin (See
control signal pulse width must be 3 PCLKs or longer to be transmitted when the Control
Signal Filter is enabled (CONFIG[1:0] = 01). There is no restriction on the minimum transition
pulse when the Control Signal Filter is disabled (CONFIG[1:0] = 00). The signal is limited to
2 transitions per 130 PCLKs.
In power-down (PDB = 0), output is controlled by the OSS_SEL pin (See
edge set by RFB function.
LOCK = 1, PLL is Locked, outputs are active LOCK = 0, PLL is unlocked, RGB[7:0], HS,
VS, DE and PCLK output states are controlled by OSS_SEL (See
as Link Status or to flag when Video Data is active (ON/OFF).
PASS = 1, error free transmission
PASS = 0, one or more errors were detected in the received payload
Route to test point for monitoring, or leave open if unused.
Operating Modes — Pin or Register Control
These pins determine the DS90UR906’s operating mode and interfacing device.
CONFIG[1:0] = 00: Interfacing to DS90UR905, Control Signal Filter DISABLED
CONFIG[1:0] = 01: Interfacing to DS90UR905, Control Signal Filter ENABLED
CONFIG[1:0] = 10: Interfacing to DS90UR241
CONFIG[1:0] = 11: Interfacing to DS90C241
SSCG Low Frequency Mode — Pin or Register Control
Only required when SSCG is enabled, otherwise LF_MODE condition is a DON’T CARE
(X).
LF_MODE = 1, SSCG in low frequency mode (PCLK = 5-20 MHz)
LF_MODE = 0, SSCG in high frequency mode (PCLK = 20-65 MHz)
; for a Low State, the IO includes an internal pull down. The STRAP pins are read upon
