The XMI contains sector RF transceivers and integrated sector TX RF Linear Power Ampliﬁers (LPAs).
PAGE 56
1X UBS Macro BTS FRU XMI (Transceiver Module Internal) Module The XMI has the following items: • Main XMI processor/memory. This processor communicates with the XPAC, RX and TX circuits, MMI and ENET (LMT) ports, and the controller in the DMI via the CPRI links. • Phase-locked loop (PLL) reference clock circuit that is synchronized to CPRI link serial data input from the DMI. This clock reference signal is used to frequency synthesize all RX & TX local oscillators.
PAGE 57
XMI (Transceiver Module Internal) Module Chapter 7: XMI Replacement Procedures RX Main & RX Diversity Signal Handling In the UBS Macro frame, the main RX antenna signal from each sector IDRF (Integrated Duplexer RX Filter) is applied to the corresponding sector main RX RF input of XMI 1. This input is applied to the main receiver path of the corresponding XMI 1 sector receiver.
PAGE 58
1X UBS Macro BTS FRU XMI (Transceiver Module Internal) Module XMI High-speed Serial data Links (HSL) The XMI has redundant 1.2288 Gbps high-speed serial data links, one link per HSL 1 and HSL 2 data ports on the front panel of the XMI. These data ports, on the XMI, are connected to the high-speed serial data interface on the DMIs. The high-speed serial data link has a multiplexed serial data signal that contains RX/TX sector-carrier trafﬁc and overhead data as well as any DMI/XMI communications data.
PAGE 59
XMI (Transceiver Module Internal) Module Chapter 7: XMI Replacement Procedures TX RF Small Signal Handling For 800 MHz XMIs, the TX RF small signal from each sector RF transmitter in the XMI is routed to the TXD connector on the front panel of the XMI. When the TXD connector is properly terminated, each sector TX RF path is completed and the TX RF small signal from each sector RF transmitter in the XMI is applied to the 3-sector TX RF input FTM.
PAGE 60
1X UBS Macro BTS FRU XMI (Transceiver Module Internal) Module XPAC Functions The XMI PA Controller (XPAC) communicates with the XMI processor and controls/monitors the following XMI circuits: • 3-sector TX RF output FTM. • Three multi-carrier TX RF LPA sections; one LPA section for each sector. • Five cooling fans in the fan tray mounted on the rear of the XMI. The XPAC and the XMI processor exchange control data and status/alarm messages via a dedicated serial bus.

XMI (Transceiver Module Internal) Module Chapter 7: XMI Replacement Procedures Connectors/Ports The following text describes each connector/port on the XMI front panel. • +27V & RTN - XMI DC input power connections. Connects to corresponding XMI DC power connector on the PDU of the UBS Macro frame. The PDU XMI DC power connector supplies protected +27 V via a 90 A circuit breaker. The +27V pin is the positive feed and RTN (i.e., DC ground) pin is the negative return.

1X UBS Macro BTS FRU XMI (Transceiver Module Internal) Module MMI and LMT ports are for debug purposes and are not intended for use by customer service personnel. • MMI - Debug RS-232 port allows the operator MMI access to the XMI MCU controller via a computer terminal through either a modem or a null modem cable. The MMI port is an 8-pin RJ-45 connector. • LMT - This port is intended for development use only.
PAGE 65
XMI (Transceiver Module Internal) Module Chapter 7: XMI Replacement Procedures XMI “HOT" Warning Label Details The XMI has a “HOT" warning label attached to it (see Figure 7-1 for label location and indications). The hot warning label senses the surface temperature of the metal XMI housing. When the XMI surface temperature reaches 50 degrees C, the “HOT" warning is fully visible indicating that the XMI is too hot to touch and may cause burns.
PAGE 66
