Description:
The LT-CR-VC-50M-1409 is the newest addition to ZR’s line of VCXOs. The standard part offers an ultra-tight stability of ±25 ppm over -40ºC to +85ºC across a supply voltage 3.3V±5%. The LT-CR uses a high refresh rate, or frequency calibration rate, to maintain a linear frequency output during temperature compensation. The 14.3 mm x 9.3 mm x 6.5 mm ceramic package and options for 1,000- or 3,000-piece reels make these components ideal for satellite communication, military communication equipment, base station, test and measurement equipment.
