Supply Voltage Power-up Sequence
Caution:
The IXP2800/IXP2850 has a prescribed supply voltage bring-up sequence that must be followed or
permanent damage to the device may result.
4.2.1
Sequence for 1.4 / 1.0 GHz Devices
The sequence for the 1.4 / 1.0 GHz B-stepping devices is as follows:
1. The 2.5 V supply must come up before the 1.3 V supply.
2. The 1.3 V supply must come up after the 2.5 V supply and must not start to ramp until the
2.5 V supply has reached greater than 1 V.
3. The 3.3 V supply must come up only after the 2.5 V and 1.3 V supplies are up and stable.
a. It is acceptable to ramp the 1.3 V and 3.3 V supplies together as long as the two supplies
rise linearly together and do not deviate by more than 10% of the nominal ramp rate until
both supplies reach their respective final voltage levels.
It is expected that all supplies will be up and stable within the maximum power-up time
requirement of 700 ms. Additionally, the maximum time from when the 2.5 V supply is up and
stable to when the 1.3 V supply begins to ramp should not exceed 200 ms.
Note:
The 1.8 V and 1.5 V supplies can come up in any order before or after the 2.5 V, 1.3 V, and 3.3 V
supplies.
Note:
No 3.3 V devices should drive any of the IXP2800/IXP2850 pins until its 3.3 V supply is up and
stable.
4.2.2
Sequence for 650 MHz Devices
The sequence for the 650 MHz B-stepping devices is as follows:
1. The 2.5 V supply must come up before the 1.2 V supply.
2. The 1.2 V supply must come up after the 2.5 V supply and must not start to ramp until the
2.5 V supply has reached greater than 1 V.
3. The 3.3 V supply should begin to ramp after the 2.5 V and 1.2 V supplies are up and stable.
a. It is acceptable to ramp the 1.2 V and 3.3 V supplies together as long as the two supplies
rise linearly together and do not deviate by more than 10% of the nominal ramp rate until
both supplies reach their respective final voltage levels.
It is expected that all supplies will be up and stable within the maximum power-up time
requirement of 700 ms. Additionally, the maximum time from when the 2.5 V supply is up and
stable to when the 1.2 V supply begins to ramp should not exceed 200 ms.
Note:
The 1.8 V and 1.5 V supplies can come up in any order before or after the 2.5 V, 1.2 V, and 3.3 V
supplies.
Note:
No 3.3 V devices should drive any of the IXP2800/IXP2850 pins until its 3.3 V supply is up and
stable.
