Hello,
I have question regard pins mentioned above:
- For PRE_SEL TI writes in the datasheet as below (which doesn't mention what is the config for I2C_EN/PIN = high):
De-emphasis pin strap when I2C_EN/PIN = Low.
PRE_SEL = L: - 2 dB de-emphasis
PRE_SEL = No Connect: 0 dB
PRE_SEL = H: Reserved
How should I config this pin if I use pin I2C_EN/PIN = high? (pull up to Vcc or pull down to GND?)
b. For SLEW_CTL TI writes in the datasheet:
Slew rate control when I2C_EN/PIN = Low.
SLEW_CTL = H, fastest data rate
SLEW_CTL = L, 5 ps slow
SLEW_CTL = No Connect, 10 ps slow
When I2C_EN/PIN = High Slew rate is controlled through I2C
What does it mean: "Slew rate is controlled through I2C" – how should I config this pin? (pull up to Vcc or pull down to GND?)
Thank you,
Edan
