Exceeding these limits may cause permanent damage. 2. Static sensitive, observe appropriate handling precautions. 3. An external series resistor and bypass capacitor will allow operation at higher supply voltage and will improve power supply decoupling and noise suppression. Environmental Specifications Devices are designed to function over the operating temperature range (TOP) of -40°C to +85°C and after exposure to the shock, vibration, thermal shock and moisture conditions typically encountered in base station and other infrastructure environments. Typical Performance Ordering Information Synthesizers are available in either tape and reel or tube packaging. To order devices in tape and reel requires the suffix TR to be added to the part number, i.e. MLS9208-01800TR. Quantity 500 per 13 inch reel, see Application Note M2030.
