Chapter 1. INTRODUCTION Overview Figure 1-1. CRS-170A L-Band 1:1 Redundancy Switch The CRS‐170A L‐Band 1:1 Redundancy Switch module, shown in Figure 1‐1, is an L‐Band Tx‐Rx IF signal switch designed for use with L‐Band satellite modems in a 1:1 configuration. The Tx (transmit) side switches four modem output signals that are multiplexed onto the transmit coaxial cable: • 950‐1950 MHz L‐band transmit RF; • 10 MHz BUC frequency reference; • 600 KHz BUC FSK control and status communication; • BUC DC power supply. The Rx (receive) side of the switch uses both power dividers and relays to provide the redundant modem interface for three signals multiplexed onto the LNB coaxial cable: • 950‐1950 MHz L‐band receive RF from LNB; 1–1...

CRS-170A L-Band 1:1 Redundancy Switch Revision 9 Introduction MN/CRS170A.IOM At the heart of the CRS‐150 is a Controller State Machine that is responsible for fault monitoring and control of switching functions – it is implemented in a CPLD. The CRS‐150 redundancy switch derives its operating power from the two modems (online and standby units) via extra power‐carrying wires in the data cable from each modem. Similarly, the CRS‐170A derives its +12V power from both modems through 'Y' cable connection to the same cables. The required online and offline control signals are also included in these cables. A diode sharing arrangement with a current sharing circuit ensures that power is taken equally from the two modems in normal operation. In the event that one of the two units is removed, however, the remaining modem can supply all current requirements. The modems supply +12 volts DC (at a combined total of 400 mA max) and ‐12 volts DC (at a combined total of 120 mA max). Maximum power consumption occurs in a serial LVDS mode at maximum data rate (20 Mbps). Power consumption in RS‐232 modes is ...
