PL500-37TC

(Preliminary) PL500-37 Low Phase Noise VCXO (36MHz to 130MHz) FEATURES   VCXO output for the 36MHz to 130MHz range Low phase noise (-148 dBc @ 10kHz offset at 77.76MHz). CMOS output with OE tri -state control. 36 to 130MHz fundamental crystal input. Integrated high linearity variable capacitors. 8mA drive capability at TTL output. +/- 150 ppm pull range, max 5% linearity. Low jitter (RMS): 2.5ps period jitter. Single 2.5V ±10% or 3.3V ±10 power supply. Operating temperature range from -40C to +85C Available in Die or Wafer form or SOP-8L or SOT23-6L packaging.

The very low jitter (2.5 ps RMS period jitter) makes this chip ideal for applications requiring voltage controlled frequency sources. The input crystal frequency can range from 36 to 130MHz (fundamental resonant mode). ^: Denotes internal Pull-up 32 mil 8 1 2 39 mil Value Size 39 x 32 mil Reverse side GND Pad dimensions 80 micron x 80 micron Thickness 8 mil XIN XOUT OE^ 7 DIE SPECIFICATIONS Name (812,986) OE^ VDD 6 3 VCON CLK 5 4 GND Y (0,0) X BLOCK DIAGRAM XIN XOUT XTAL OSC VARICAP OE VCON Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1(408) 944 -0800 • fax +1(408) 474-1000 • www.micrel.com Rev 7/05/10 Page 1 (Preliminary) PL500-37 Low Phase Noise VCXO (36MHz to 130MHz) PIN AND PAD ASSIGNMENT AND DESCRIPTION Name XIN Pin# Die Pad Position SOP-8 SOT23-6 X (m) Y (m) 1 3 94.183 768.599 2 - 94.157 605.029 OE Type Description I Crystal input pin.

If the crystal requires more load to be at nominal frequency, the additional load must be added externally. This ho wever may reduce the pull range.
