# 不可微调
## TCXO 温补
ECS-VTXO-2520-100
不可调32255032 可调
ASTX-H11-10.000MHz(3225)
无100MHz温补一般不超过50MHz 相噪一般 -135dBc/Hz@1kHz -145dBc/Hz@10kHz
## OSC 音频晶振(不可调)
AS318-B-100S-1 2520封装
100MHz相噪很好 便宜 10元一片 -146dBc/Hz@1kHz -163dBc/Hz@10kHz
# 可微调
NDK公司的NT5032BA系列可以微调指标也好
典型可调频率范围4.6ppm温度漂移0.28ppm
DSA321SDN10MHz±0.5ppm3225封装
可调, -135dBc/Hz@1kHz
# 供电
温补晶振典型电流消耗不超过10mA建议采用TL431供电以减弱外部电源波动带来的影响
