General Description
The DS4026 is a temperature-compensated crystal
oscillator (TCXO) that provides ±1ppm frequency stabili-
ty over the -40°C to +85°C industrial temperature range.
The DS4026 is also available in Stratum 3 versions (see
the
Ordering Information—Stratum 3 table). Each device
is factory calibrated over temperature to achieve the
±1ppm frequency stability. Standard frequencies for the
device include 10, 12.8, 19.44, 20, 38.88, 40, and
51.84MHz. Contact the factory for custom 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 20 years. The device also
provides an I2C interface to allow pushing and pulling
of the output frequency by a minimum of ±8ppm
(±5ppm for 10MHz) 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 voltage-controlled crystal oscillator to compensate
for frequency change.
The device implements an on-chip temperature sensor
lookup table, and a digital-to-analog converter (DAC) to
adjust the frequency. An I2C interface used to commu-
nicate with the DS4026 performs temperature readings
and frequency push-pull.
