Crystal Clock Oscillator
NZ2520SEA
High-precision Crystal Clock Oscillator
Application
■
● WiLAN, WiMAX, Bluetooth, PLC, UWB, Car-electronics connection.
Features
■
This device is a new SPXO of hold over frequency tolerance as tight as
±15×10–6(–40 to +85°C) by building a temperature compensating circuit in it.
CMOS output despite temperature compensated circuit. This device reduces harmonics level
to prevent the interference with the radio frequency by the wireless communication use.
● Overall Frequency Tolerance Max. ±15×10–6 at –40 to +85°C.
● Harmonics level reduce.
● Conventional ratio about -17dBm at Output 40MHz, VCC 2.8V, 2.4GHz band.
● Package Size : 2.5 × 2.0 × 0.9mm
Absolute maximum rating
Supply Voltage (VCC) –0.6 to +6.0 V
Storage Temperature Range –55 to +125 °C
