GENERAL DESCRIPTION
The DS4000 digitally controlled temperature-compensated crystal oscillator (DC-TCXO) features a digital temperature sensor, one fixed-frequency temperaturecompensated square-wave output (F1), one programmable temperature-compensated squarewave output (F2), and digital communication for frequency tuning (SDA, SCL).
FEATURES
§ § § Aging ≤1.0ppm (First Year) Frequency Stability ±1.0ppm from -40°C to +85°C Frequency Versus Supply Stability of ±1.0ppm per Volt Base Frequency is Digitally Tunable by ±10ppm One Fixed-Frequency Output and One (n + 1) or 2(n + 1) Division of the Base Frequency Output Temperature Measurements from -40C° to +85°C with 10-Bit/+0.
