The AMC004 provides a complete GPS bus-level timing solution to a μTCA/ATCA system. The on-board GPS receiver is used to discipline the local oscillator and cancel out any oscillator drift or aging. Precision UTC timestamps and GPS location/time/status are all made available via PCIe/SRIO registers to the host CPU/application. Time trigger output and time event interrupts synchronized to GPS UTC are available under host control. GPS location/time/status data Broadcast/Unicast output via backplane Ethernet with selectable bonding/failover behavior. The disciplined clock, 1PPS, divided-down clock, and time trigger may be output in any combination to the TCLKA / TCLKB / TCLKC / TCLKD backplane channels. PPS IN synchronization pulse usually comes from the on-board GPS but can alternatively come from the front/back inputs if the GPS signal is not available.

A backup battery or SuperCap provides non-volatile storage of the Almanac, Ephemeris, and Last position data to enable rapid "warm start" re-acquisition usually within 35 seconds. The module has a serial port in the front that enables advanced configuration and monitoring support. Locking/holdover status is also available via IPMI sensors. A secondary serial port enables NMEA data in/out.
