APPLICATIONS
The Model 520 Temperature Compensated Crystal Oscillator (TCXO) is a quartz
based, clipped sine wave output, with optional frequency tuning, in a hermetically
sealed ceramic package. M520 is suitable for wireless communications, broadband access,
WLAN/WiMax/WIFI, portable equipment, test and measurement and mobile applications.
ORDERING INFORMATION
3] Frequency is recorded with two leading digits before the ‘M’ and 4 significant digits after the ‘M’ (including zeros).
1] Only available with temperature range codes "H" and "C".
Not all performance combinations and frequencies may be available.
M = +1.8Vdc
N = +2.5Vdc
= +2.8Vdc
R = +3.0Vdc
L = +3.3Vdc
