UNDP-1 Universal Notebook Data Platform User Guide DC Power and UNDP Operating Modes

3.2 DC power states

Based on applied DC power and control signals from the host computer, the UNDP-1

platform is set to one of four DC power states, as shown in Table 3-1.

3.3 UNDP operating modes

Example UNDP-1 platform operating modes and their expected data throughput rates are

summarized in Table 3-2. Operating modes are set by the host computer via the USB

interface.

Table 3-1 UNDP-1 DC power states

Normal and low power states are set by the host computer via the USB interface.

State Description

Disconnected DC power is not applied to the UNDP-1 platform.

Off DC power is applied to the UNDP-1 platform, but the platform is disabled

via the W_DISABLE_N control signal.

Normal DC power is applied to the UNDP-1 platform, the platform is enabled via

the W_DISABLE_N control signal, its USB interface is active, and it is

operating in one of the following modes:

■ One of the active airlink modes listed in Table 3-2 (with or without GPS

position location)

■ Powerdown

■ Sleep

Low power DC power is applied to the UNDP-1 platform, the platform is enabled via

the W_DISABLE_N control signal, and its USB interface is active.

However, the airlink (and all supporting RF, LO, and baseband circuits) is

disabled.

Table 3-2 UNDP-1 operating modes and throughput rates

GPS position location can be enabled simultaneously with any airlink operating mode, or Rx

diversity can be enabled during any CDMA or WCDMA operating mode.

Data throughput rate

Target peak data rates are listed; actual throughput performance varies depending on

operating and RF environment conditions.
