• Developed for CDMA cellular phone (Low noise level: -120
dBc/Hz Typ. at 100 Hz offset, fo = 19.68 MHz
• Power saving function (standby function)built-in. (TG-2824CB)
• Reflowable and high density mounting type ultra small size SMD. (5.0x3.2x1.5 mm)
• Using the heat-resisting type AT cut quartz crystal
allows almost the same temprature soldering as universal SMD IC.
• Operating supply voltage : 2.8 V.
