Description
00: Control Signal Filter DISABLED. Interfaces with DS92LV2411 or DS92LV0411
01: Control Signal Filter ENABLED. Interfaces with DS92LV2411 or DS92LV0411
10: Reverse compatibility mode to interface with the DS90UR241 or DS99R241
11: Reverse compatibility mode to interface with the DS90C241
SSCG Low Frequency Mode
Only required when SSCG is enabled, otherwise LF_MODE condition is a DON’T CARE
(X).
LF_MODE = 1, SSCG in low frequency mode (CLK = 5-20 MHz)
LF_MODE = 0, SSCG in high frequency mode (CLK = 20-50 MHz)
This can also be controlled by I2C register access.
Output CLKOUT Slew Select
OS_CLKOUT = 1, Increased CLKOUT slew rate
OS_CLKOUT = 0, Normal CLKOUT slew rate (default)
This can also be controlled by I2C register access.
Output DO[23:0], CO1, CO2, CO3 Slew Select
OS_DATA = 1, Increased DO slew rate
OS_DATA = 0, Normal DO slew rate (default)
This can also be controlled by I2C register access.
Outputs held LOW when LOCK = 1
NOTE: Do not use any other strap options with this strap function enabled
OP_LOW = 1: all outputs are held LOW during power up until released by programming
OP_LOW release/set register HIGH.
NOTE: Before the device is powered up, the outputs are in TRI-STATE™
See
OP_LOW = 0: all outputs toggle normally as soon as LOCK goes HIGH (default)
This can also be controlled by I2C register access.
Output Sleep State Select
OSS_SEL is used in conjunction with PDB to determine the state of the outputs in Power
Down (Sleep). (See
NOTE: OSS_SEL STRAP CANNOT BE USED IF OP_LOW = 1
This can also be controlled by I2C register access.
Clock Output Strobe Edge Select
RFB = 1, parallel interface data and control signals are strobed on the rising clock edge.
RFB = 0, parallel interface data and control signals are strobed on the falling clock edge.
This can also be controlled by I2C register access.
Receiver Input Equalization
(See
This can also be controlled by I2C register access.
Oscillator Selectl
(See
This can also be controlled by I2C register access.
Spread Spectrum Clock Generation (SSCG) Range Select
(See
This can also be controlled by I2C register access.
