ABV0017 Low Phase Noise VCXO (17MHz to 36MHz) FEATURES • • VCXO output for the 17MHz to 36MHz range Low phase noise (-130 dBc @ 10kHz offset at 35.328MHz). CMOS output with OE tri-state control. 17 to 36MHz fundamental crystal input. Integrated high linearity variable capacitors. 12mA drive capability at TTL output. +/- 150 ppm pull range, max 5% linearity. Low jitter (RMS): 2.5ps period jitter. 2.5 to 3.3V operation. Available in 8-Pin SOIC XIN 1 VDD* 2 VIN 3 GND 4 ABV0017 • • • • • • • • PIN CONFIGURATION 8 XOUT 7 OE^ 6 VDD* 5 CLK ^: Denotes internal Pull-up *: Only one VDD pin needs to be connected DESCRIPTION 8-pin SOIC OUT 1 GND 2 CLK 3 ABV0017 The ABV0017 is a low cost, high performance and low phase noise VCXO for the 17 to 36MHz range, providing less than -130dBc at 10kHz offset at 35.328MHz. The very low jitter (2.5 ps RMS period jitter) makes this chip ideal for applications requiring voltage controlled frequency sources. Input crystal can range from 17 to 36MHz (fundamental resonant mode). 6 XIN 5 VDD 4 VIN FREQUENCY RANGE MULTIPLIER FREQUENCY No PLL 17 – 36 MHz OUTPUT BUFFER CMOS 6-pin SOT BLOCK DIAGRAM XIN XTAL XOUT OSC VARICAP OE VCON 30332 Esperanza., Rancho Santa Margarita, Ca 92688 Ph: 949-546-8000 Fax: 949-546-8001 www.Abracon.com 03/21/05 Page 1 ABV0017 Low Phase Noise VCXO (17MHz to 36MHz) PIN ASSIGNMENT (8-pin SOIC package) AND PAD DESCRIPTION Name Pin# Type Description XIN VDD VCON GND CLK VDD 1 2 3 4 5 6 I P I P O P OE 7 I XOUT 8 I Crystal input pin.
