ABX0027T Datasheet | Abracon Corporation

FEATURES - - 3 CMOS outputs with OE tri-state control Low current consumption: ABX0027T: <4.5m A @ 27MHz with standard CMOS buffer (3.3V) ABX0037T: <3.0m A @ 27MHz with CMOS patible Clipped buffer, offering the lowest current consumption (3.3V) 10 to 52MHz fundamental crystal input. Low phase noise (-130 d Bc @ 10k Hz offset). Low jitter (RMS): 2.5ps period jitter. 12m A drive capability at TTL output. 1.62V to 3.63V DC operation. Available in 8 pin SOIC.

In addition, they provide among the lowest current on the market for the 10MHz to 52MHz range. They accept input crystals from 10 to 52MHz (fundamental resonant mode) and provide low phase noise (<-130d Bc at 10k Hz offset at 30MHz), and very low jitter (2.5 ps RMS period jitter) outputs.
