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

T = +2.8Vdc

R = +3.0Vdc

L = +3.3Vdc

Contact your local CTS Representative or CTS Customer Service for availability.

T = TCXO (no AFC)

A = ± 5 ppm 4

2] Only available with temperature range codes "H", "C" and "D".
