UNDP-1 Universal Notebook Data Platform User Guide Introduction
The primary antenna is connected to its RF front-end circuits (a switch module, CDMA
and UMTS duplexers, etc). In the transmit direction, these front-end circuits are driven by
the transmit output chains: two chains support GSM low and high bands (GSM850 +
GSM900 and GSM1800 + GSM1900); three chains support CDMA (Cell + PCS) and
UMTS (Cell + PCS + IMT) operation. All baseband-to-RF processing - for all supported
bands - is performed within the RTR6285 IC.
The four GSM receive paths are filtered, then routed to the RTR6285 IC for processing.
The CDMA and UMTS primary receive filtering is achieved within the front-end
duplexers; the signals are then routed to either the RTR6285 IC (UMTS IMT) or the
RFR6500 IC (CDMA and UMTS Cell + PCS) for RF-to-baseband processing.
Like the primary antenna, the secondary antenna is connected to its own RF front-end
circuits (a switch module, CDMA/UMTS filters, GPS filter, etc). The filtered signals are
then routed to the appropriate RFIC for RF-to-baseband processing (RTR6285 IC for
UMTS IMT; RFR6500 for CDMA and UMTS Cell + PCS and GPS).
The MDM1000 device provides all the digital baseband processing, including modem
functions for all the supported airlinks. Integrated MDM1000 functions include the
ARM1136-J™ and ARM926EJ-S™ processor cores; two low-power, high-performance
digital signal processor (DSP) cores; and 32 MB stacked dual data rate (DDR)
synchronous dynamic random access memory (SDRAM).
UICC (RUIM/USIM) is supported via an offboard UICC connector that is implemented
per the PCI Express Mini Card specification, version 1.1. The UNDP-1 UICC interface is
compliant with GSM 11.12 and ISO/IEC 7816-3 standards.
In addition to the PCI Express Mini Card edge connector, board-level pads are provided
for interfacing to a JTAG fixture.
With its 4 MB of NOR flash memory and 32 MB of RAM (stacked DDR-SDRAM inside
the MDM1000), the UNDP-1 supports a new code storage architecture via the Qualcomm
Data Loader (QDL). The Advanced Mobile Suscriber Software (AMSS) image is stored
on the PC file system and downloaded to the UNDP-1 device RAM at system startup.
NOR flash memory contains a boot image to support the initialization and configuration of
the UNDP-1 hardware system, including the RF calibration items. It then enumerates on
the USB, and the host computer downloads the embedded software and configuration
memory items over the USB using QDL.
Software interfaces that were developed for Qualcomm chipsets are supported by the
UNDP-1 product. The QDL data card interface ISOD describes the C API functions that
PC software applications must use to interface with UNDP-1; see [1] listed within
Table 1-2 for details. The supplement to the streaming download protocol specification
describes the high-speed download protocol; see [2] within the same table for details.
The UNDP-1 platform includes the PM6653 power management IC to detect and validate
the applied DC power source, coordinate system powerup and powerdown actions,
generate all the required on-board supply voltages, implement the primary on-board clock
sources, and provide several secondary functions (such as driving the status LED).
