CPU/Receiver Module This module is present in all units and provides the standard I/O features:  1PPS, Timecode, Ethernet, RS-232, and GPS Antenna.  Optional outputs are also available from this module.  Read the Meridian & Tycho Options datasheet for more information.

Oscillator/Low Phase Noise Output Module This optional module configures the Meridian with several different 10 MHz oscillators.  Three grades of OCXOs plus two grades of rubidium oscillators are available.  Low-phase-noise outputs work with these high-performance oscillators to provide individually-buffered, spectrally pure, sinewave outputs with high channel-to-channel isolation.  Four outputs are shown on this module.

Low Phase Noise Output Module Up to 20 spectrally pure low-phase-noise outputs can be supported in a Meridian TimeBase.  The Meridian configuration shown here provides eight low-phase-noise outputs with the module to the left providing the first four outputs.  This module provides an additional four low-phase-noise outputs.

Programmable Digital Buffer Module This optional module adds four individually programmable TTL outputs to your Meridian TimeBase.  These buffered outputs provide on-time pulse rates from 1 PPS to 10 MPPS, or a digital timecode output.  (A synthesized rate output (DDS) is also available as an additional upgrade.)  Up to 22 of these TTL outputs can be supported in a single Meridian chassis.

Telecom Clock Output Module This optional module adds two outputs that can be any combination of E1, T1 or Composite Clock.  To meet the jitter/wander mask requirements for telecom applications your Meridian must have an OCXO or rubidium oscillator, which takes one or two slots.  Up to eight telecom clock outputs can be provided in the remaining slots.

Telecom Clock Output Module This optional module adds two outputs that can be any combination of E1, T1 or Composite Clock.  This particular module has an additional Alarm Output that provides relay contacts for minor, major and critical conditions.

Power Supply Module This is the power supply module, a custom designed, high performance AC-DC or DC-DC converter capable of supporting a fully loaded chassis over the full 0C to 50C temperature range in a sealed, fanless chassis.
