PL502-02SC-R

PL502-02 Low Phase Noise VCXO (24MHz to 50MHz) FEATURES      Low phase noise VCXO output for the 24MHz to 50MHz range (-130 dBc at 10kHz offset) LVCMOS output 12 to 25MHz crystal input Integrated variable capacitors Available with High Drive (30mA) or Standard Drive (10mA) output Wide pull range (± 250 ppm typical) Low period jitter: 3ps RMS 3.3V operation Available in 8-Pin SOP. XOUT 1 N/C 2 VCON 3 GND 4 PL502-02     PIN CONFIGURATION 8 XIN 7 N/C 6 VDD 5 CLK SOP-8L OUTPUT RANGE DESCRIPTION The PL502-02 is a low cost, high performance, low phase noise VCXO, providing less than -130dBc at 10kHz offset in the 24MHz to 50MHz operating range. The very low jitter (3 ps RMS period jitter) makes this chip ideal for applications requiring vol tage controlled frequency sources. Input crystal can range from 12MHz to 25MHz (fundamental resonant mode).

It is assumed that the cr ystal will be at nominal frequency at this load. If the crystal requires more load to be at nominal frequency, the additiona l load must be added externally. This however may reduce the pull range. PACKAGE INFORMATION (GREEN PACKAGE COM PLIANT) 8 PIN SOP (in mm) Symbol A A1 B C D E H L e Min.
