The LT-Series Phase-Locked DRO replacements measure 1.30 × 1.10 × 0.30 inches. Supplied as fixed-frequency or serially-programmable precision phase-locked oscillators, the LT-Series covers the frequency range (in bands ) from 200 MHz to over 8 GHz. Utilizing external 10 - 125 MHz frequency references for high stability, these products exhibit low phase noise characteristics (typically 115 dBc/Hz) at 100 kHz offset at 8 GHz carrier frequency). Operating at low voltages (+8, +5, +3.3 V DC) and very low current, the LT-Series synthesizer consumes less than 750 mW of power. Typical operating temperature range is 30°C to +70°C.
