| ABX0027B Ultra Low Current XO 10 MHz to 52 MHz FEATURES * * * * * * * * Low phase noise (-145 dBc @ 10kHz offset). CMOS output with OE tri-state control. Ultra Low current consumption ( <2mA, at 27MHz, 3.3V) 10 to 52MHz fundamental or 3 rd OT crystal input. 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 PIN ASSIGNMENT (PACKAGE) OE^ GND XIN/FIN 1 2 3 6 5 4 CLK VDD XOUT SOT-23 DESCRIPTION The ABX0027B form a low cost family of XO IC's, designed to consume the lowest current on the market for the 10MHz to 52MHz range. It accepts fundamental 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 period jitter) makes this chip ideal for applications requiring low current frequency sources.
