Seoan developed the 800MHz high frequency VCXO the end of 2010 and is developing 1GHz VCXO for the digital clock of the mobile communication system. Seoan's 800MHz VCXO is applicable for Repeator of KT(Korea Telecom :Mobile Communication Service Company). Seoan's 800MHz VCXO is developed to replace the world leader manufacturer's 800MHz VCXO by request of a repeator provider to KT because of cost and delivery. The phase noise characteristic of Seoan’s 800MHz VCXO is better than competitor’s 800MHz VCXO. The brief specifications are as follows.
- Frequency stability < ±25ppm @ -40~+85℃
- Frequency Tuning > ±100ppm @ 3.3 & 0.0V
- Phase Noise > 140dBc @ 100kHz
- Size : 16x9x6mm
