FEATURES
VCXO output for the 17MHz to 130MHz range - PLL500-17B: 17MHz to 36MHz - PLL500-27B: 27MHz to 65MHz - PLL500-37B: 65MHz to 130MHz Low phase noise (-142 dBc @ 10kHz offset). CMOS output with OE tri-state control. Selectable output drive (Standard or High drive). - Standard: 8mA drive capability at TTL level. - High: 24mA drive capability at TTL level. Fundamental crystal input. Integrated high linearity variable capacitors. +/- 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 or DIE.
DESCRIPTION
The PLL500-17B/27B/37B are a low cost, high per- formance, low phase noise, and high linearity VCXO family for the 17 to 130MHz range, providing less than -130dBc at 10kHz offset. The very low jitter (2.5 ps RMS period jitter) makes these chips ideal for applications requiring voltage controlled frequency sources. The IC’s are designed to accept fundamen- tal resonant mode crystals.
