TME-SMD2520
Manufacturer: Hosonic
The TME-SMD2520 is a voltage-controlled crystal oscillator, meaning its output frequency can be pulled slightly by an external control voltage. That is what a phase-locked loop needs in order to lock onto an incoming reference and track it. The pull range is ±15 ppm, and the part sits in a 2520 package.
Overview
The TME-SMD2520 is a voltage-controlled TCXO (VCTCXO) from Hosonic with a nominal frequency of 10.000000 MHz. The datasheet specifies a 3 V supply, a frequency stability of ±0.5 ppm over the -40 to +85 °C range and a pulling range of ±5 ppm, which is what makes it useful for locking a reference to an external control voltage. Stability against supply and against load is specified with a 10 kΩ // 10 pF reference load.
The part is supplied in the 2520 package and is aimed at telecom, base station and instrumentation designs where a compact oscillator must be trimmed electrically, for example to steer a PLL or to correct frequency during service life.
Key features
- Analog frequency control for PLL locking and tracking
