5x7mm
Precision TCXO
In Stock at Digi-Key
Description:
Features:
The Connor-Winfield’s D75A is a 5x7mm
Surface Mount Temperature Compensated
Crystal Controlled Oscillator (TCXO) with
a Tri-State LVCMOS output. Through the
use of Analog Temperature Compensation,
the D75A is capable of holding sub 1-ppm
stabilities over the 0 to 70°C temperature
range. The D75A meets STRATUM 3
requirements.
