    HC - 49S Quartz Crystal Oscillator Dip Oscillator And Crystal product application 1, Audio products 2, widely used in MP3 3, DVD 4, digital products product features The crystal is usually matched with the PLL circuit, the clock frequency to provide system required. If different subsystems need different frequency clock signal can be used in different phase locked loop is connected with the same crystal to provide. Standard Environmental Condition: Environmental Temperature:15~35 Humidity:45%~85% Atmospheric pressure:86~106KPa Operating Temperature Range:-20~70 Crystal Frequency & Resistance will be tested under the following conditions, Unless extra requirments: standard temperature(252) after heat balance. Storage Temperature Range:-40~+85 Mechanical test: The quartz crystal unit shall be subjected to normal atmospheric conditions for 1hr before being tested. Dropping Test: The Units are measured for its frequency and resistance in accordance with Table1 & without mechanical damage, after allowing the crystal to fall freely. From 75 cm of height 3 times on the firmed wood. Vibration Test: The Units are measured for its frequency and resistance in accordance with Table 1&without mechanical damage afer subjectiong to 2hrs of vibration with 0.75mm amplitude with 10~55Hz frequency sweep 20 times. 4.1.3 Sealing Tightness: Find Lead Test:110-8atmcc/S by Helium mass-mass-spectrometer detector, and vacuum and reach 110-3Pa Resistance to Soldering Heat: The Units are measured for its frequency and resistance in accordance with Table 1 after dipping into molten solder with the temperature of 32010For 3~4 secs and at a depth up to a point 2.0mm from the base root.
