Product Information

Primary Reference Source for Public Networks

Microchip’s TimeSource 3×50 is an easy to deploy GPS based Primary Reference Source for frequency based digital networks. The TimeSource GPS uses a Two-Way Time Transfer Protocol, allowing the use of smaller diameters and thus easier to deploy cable systems. The TimeSource can also include external frequency inputs to deliver 2 or 10 Stratum 1 outputs using either OCXO 1 OCXO = Oven Controlled Crystal Oscillator or Rubidium Atomic Clock holdover.

TimeSource 3050 with a high-quality OCXO provides your network with Stratum 1 performance when locked to GNSS or up to 72 hours if GNSS signals are interrupted.

TimeSource 3050 consists of single unit modules that plug into a rack-mounted shelf. TimeSource 3050 operates with an external high precision GPS timing antenna to meet GR-2830 and EN 300 462-6-1 requirements. It comes with two output ports that are software configurable for T1, E1, 2.048 MHz or composite clock to support frequency timing applications; there is also a SW License option for 8 additional outputs.

The TimeSource 3050 modules may be used on previously supplied shelves of TimeSource 3100 products.

Improved GPS antenna design

The new GPS rooftop antennas for the TimeSource 3050 provide advanced narrow band filtering to protect against interference from adjacent spectrum. They also provide automatic compensation for cable delays via TWTT 2 TWTT = Two-Way Time Transfer . The GPS antenna can be installed up to 1,000 feet from the office shelf, without amplifiers, using an inexpensive thin coax cable.

Environmentally friendly

Energy-efficient hardware yields substantial OPEX savings with dramatically reduced power consumption. The product is also fully ROHS 3 ROHS = Restriction of Hazardous Systems  6/6 compliant.
