Third-generation OEM GPS clock module offers accurate DAB-T, DVB-T synchronization Jan 9, 2004 12:00 PM France -- TEKELEC is completing work on its new OEM GPS clock module designed to anticipate the future Digital Broadcasting transmission network infrastructures (DAB-T and DVB-T). The Epsilon OEM Board (EBO III-ER) is designed to fit in both MFN (multifrequency network) and SFN (single-frequency network) transmission equipment to allow minimum network evolution cost. In addition to its enhanced second-generation board feature, this product offers an external network source (10 MHz or 1 pps) to be used as reference signal or as a back-up source in case of GPS loss. By launching this third-generation module, TEKELEC will provide transmitter manufacturers a product with accurate and stable frequency generation, a low phase noise and spurious level, a unique time source with 25 nanosecond accuracy to UTC (Coordinated Universal Time), a permanent phase locking of time and frequency using a common GPS source, fast warm-up, and the ability to upgrade to GPS (set as primary or secondary source).
The combination of an external reference, a GPS signal, a simple or double oven OCXO (oven-controlled crystal oscillator) with its proprietary Kalman Algorithm filter delivers holdover for transmission network infrastructures. The company is currently seeking business contacts in both the United States and Canada.
