T2SB26E004200E
Manufacturer: Hosonic
The T2SB26E004200E is a 26 MHz crystal unit in an SMD2520 package with an integrated thermistor. The thermistor is the notable feature: it lets the host measure the crystal temperature directly and apply frequency correction in software, which is how phone and RF platforms keep timing on-frequency across temperature without the cost of a full TCXO.
Overview
The T2SB26E004200E is a 26 MHz SMD crystal from Hosonic with an NTC thermistor built into the package. The thermistor lets the host measure the crystal temperature in real time and apply software temperature compensation, the usual way to hold a wireless reference steady without the cost of a TCXO. Nominal frequency is 26 MHz with a tolerance of ±10 ppm, and the part is specified over -30 to +85 °C.
The package is the 2520 chip outline, which saves board area in the RF section. Applications are Wi-Fi, Bluetooth and general wireless modules where the radio needs a temperature-aware reference clock.
Key features
- Integrated thermistor enables software frequency compensation
- 2520 package suits space-constrained RF and module boards
- 26 MHz suits RF reference and application processor clocks
Typical applications
- Smartphone and tablet RF reference
- Wireless modules requiring temperature compensation
- GPS and connectivity timing
