FEATURES

• Low phase noise (-145 dBc @ 10kHz offset).

• CMOS output with OE tri-state control.

• Ultra Low current consumption ( <2mA, at

27MHz, 3.3V)

• 12mA drive capability at TTL output.

• Low jitter (RMS): 2.5ps period jitter.

• 1.8V, 2.5V and 3.3V DC operation.

• Available in 6 pin SOT-23

DESCRIPTION

The ABX0027B form a low cost family of XO IC’s,

designed to consume the lowest current on the mar-

ket for the 10MHz to 52MHz range. It accepts fun-

damental resonant mode crystal input from 10 to

52MHz. Providing less than -145 dBc at 10kHz offset

at 30MHz and with a very low jitter (2.5 ps RMS pe-

riod jitter) makes this chip ideal for applications re-

quiring low current frequency sources.
