Environmental Specifications
Devices are designed to function over the operating temperature
range (T_OP) of -40°C to +85°C and after exposure to the shock,
vibration, thermal shock and moisture conditions typically encoun-
tered in base station and other infrastructure environments.

1. Exceeding these limits may cause permanent damage.
2. Static sensitive, observe appropriate handling precautions.
3. An external series resistor and bypass capacitor will allow opera-
tion at higher supply voltage and will improve power supply decou-
pling and noise suppression.
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. MLS9228-01760TR. Quantity 500
per 13 inch reel, see Application Note M2030.
