Oscillator JT21S(V) · (VC)TCXO

Product catalog summary

Overview: The document provides technical specifications for the JT21S and JT21SV oscillators, which are temperature-compensated crystal oscillators (TCXO) and voltage-controlled temperature-compensated crystal oscillators (VCTCXO) respectively. These components are designed for low power consumption and are suitable for navigation systems.

Specifications:

Frequency Range: 9.5 to 52.0 MHz
Frequency Tolerance/Stability: At +25°C ±2.0 ppm including 2x reflow; temperature stability ranges from ±0.5 ppm to ±5 ppm depending on the temperature code.
Aging: ±1 ppm in the first year
Supply Voltage: Options include 1.8, 2.5, 2.8, 3.0, and 3.3 VDC with a tolerance of ±5%
Current Consumption: 1.5 mA max for frequencies <26 MHz and 2.5 mA max for frequencies <52 MHz
Output Load: Nominal 10 KΩ // 10 pF with a minimum level of 0.8 Vpp (clipped sine)
External Tuning Range (JT21SV): ±8 ppm min.
Phase Noise: -117 dBc/Hz at 100 Hz, -137 dBc/Hz at 1 KHz, and -149 dBc/Hz at 10 KHz

Temperature Stability: The document includes a table detailing frequency stability across various operating temperature codes, ranging from -40°C to +85°C.

Pin Configuration:

JT21S: Pin #1 and #2 are GND, #3 is output, #4 is VDC
JT21SV: Pin #1 is Vcontrol, #2 is GND, #3 is output, #4 is VDC

Additional Notes: External AC coupling for output is recommended. The document also mentions compliance with RoHS and REACH standards, and the availability of conflict mineral-free components.

Order Information: Includes details on oscillator frequency, type, supply voltage, control voltage, frequency stability code, and operating temperature code.

Packaging and Soldering: Standard packing unit is 500 pieces per reel, with customized quantities available on request. The reflow soldering profile is provided, indicating temperature and time specifications for soldering processes.
