Baseband HW Introduction This document specifies the baseband module for the Nokia 1100. The baseband module includes the baseband engine chipset, the UI components and the acoustical parts for the transceiver.
RH-18/36/38 Company confidential Engine module CCS Technical Documentation The UEM ASIC mainly handles the interface between the baseband and the RF section. UEM provides A/D and D/A conversion of the in-phase and quadrature receive and trans- mit signal paths and also A/D and D/A conversions of received and transmitted audio sig- nals to and from the user interface.
Company confidential RH-18/36/38 CCS Technical Documentation Engine module mode UEM enters RESET mode (after 20ms delay), if any of following statements is true (logical OR –function): – Power_on button detected (PWROFFX) – charger connection detected (VCHARDET) – RTC_ALARM detected The Phone enters POWER_OFF mode from all the other modes except NO_SUPPLY if internal watchdog elapses.

Company confidential RH-18/36/38 CCS Technical Documentation Engine module Baseband – RF interface The interface between the baseband and the RF can be divided into three categories: - The digital interface from the UPP to the RF ASIC (Mjoelner). The serial digital interface is used to control the operation of the different blocks in the RF ASICs.

Company confidential RH-18/36/38 CCS Technical Documentation Engine module Memory Module The baseband memory module consists of external burst flash memory 2Mbyte (16Mbit) (optional: 4Mbyte (32Mbit) or 8MByte (64Mbit)). The UPP contains internal SRAM with 2 Mbit (optional: 4Mbit or 8Mbit). The UPP will not be covered here.
RH-18/36/38 Company confidential Engine module CCS Technical Documentation Test Interfaces The test pattern is placed on engine PWB, for service and production purposes, same test pattern is used for after sales purposes as well. Through MBUS or FBUS connections, the phone HW can be tested by PC software (Phoe- nix) and production equipment (FLALI/FINUI/LABEL).
Company confidential RH-18/36/38 CCS Technical Documentation Engine module General description of the RF circuits In the following general descriptions different colours are used in the block diagram. The GSM 850 signal route is shown in red, the GSM1900 route in green and the common sig- nal lines are shown in blue.
RH-18/36/38 Company confidential Engine module CCS Technical Documentation Transmitter signal path The I/Q signal from the BB is routed to the modulators for both 850 and 1900 MHz. The output of the modulators is either terminated in a SAW filter (Z603) for GSM 850 or a balun for GSM1900.
