General Description
The DS4026 is a temperature-compensated crystal
oscillator (TCXO) that provides ±1ppm frequency sta-
bility over the -40°C to +85°C industrial temperature
range. Each device is factory calibrated over tempera-
ture to achieve the ±1ppm frequency stability. Standard
frequencies for the device include 12.8, 19.44, 20.0,
38.88, 40.0, and 51.84MHz. Contact the factory for cus-
tom frequencies.
The DS4026 provides excellent phase-noise characteris-
tics. The output is a push-pull CMOS square wave with
symmetrical rise and fall times. In addition, the DS4026 is
designed to provide a maximum frequency deviation of
less than ±4.6ppm over 10 years. The device also pro-
vides an I
2
C interface to allow pushing and pulling of the
output frequency by a minimum of ±15ppm typical with
typical 1ppb resolution.
The DS4026 implements a temperature-to-voltage con-
version with a nonlinear relationship. The output from the
temperature-to-voltage converter is used to drive the volt-
age-controlled crystal oscillator to compensate for fre-
quency change.
The device implements an on-chip temperature sensor
lookup table, and a digital-to-analog converter (DAC) to
adjust the frequency. An I
2
C interface used to communi-
cate with the DS4026 performs temperature readings and
frequency push-pull.
