TimeProvider 100 Functional Block Diagram

TimeProvider 100 accepts the Radio Frequency (RF) signal from a GPS antenna. In
the Real Time Engine (RTE) circuit, the 1 PPS signal is extracted from the GPS
signal and is used to discipline the 10 MHz oven-controlled crystal oscillator
(OCXO). Both the 1 pulse per second (PPS) and 10 MHz signals are provided as
outputs from BNC connectors.
Note: When using the CLI commands, the RTE (Real Time Engine) is
referred to as "TimeMAX."
The 10 MHz reference signal and the 1 PPS signal from the RTE circuit are used to
generate 2.048 MHz frequency signals and E1 synchronization signals.
TimeProvider 100 provides multiple E1 frame formats. There are four outputs; each
is independently programmable to output either a framed or unframed
synchronization signal or a square wave clock signal as shown in
