It allows the control of the output frequency with an input voltage (VCON), using a low cost 12MHz to 25MHz crystal. This one IC can be used to produce a VCXO with output frequencies ranging from F XIN / 16 to F XIN x 32 thanks to the four frequency selector pads. This makes the PL502-30 ideal as a universal die for applications ranging from ADSL to SONET. 2 GND (0,0) Y GND 1 DESCRIPTION (1550,1475) C502 GND         750kHz to 800MHz output range Low phase noise output  -127dBc/Hz for 155.52MHz @ 10kHz offset  -115dBc/Hz for 622.08MHz @ 10kHz offset Selectable LVCMOS, LVPECL or LVDS output Selectable High Drive or Standard Drive LVCMOS 12MHz to 25MHz crystal input No external load capacitor or varicap required Output Enable selector Wide pull range (±200ppm) 3.3V operation Available in Die form (65 mil x 62 mil) OUTSEL0^   DIE CONFIGURATION 62 mil FEATURES 0 1 (Default) Selected Output OE_CTRL (Pad #30) State 0 (Default) Output enabled 1 Tri-state 0 Tri-state 1 (Default) Output enabled Pad # 9: Bond to GND to set to “0”, bond to VDD to set to “1” Pad # 30: Logical states defined by PECL levels if OE_SELECT is “0” Logical states defined by CMOS levels if OE_SELECT is “1” Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1(408) 944 -0800 • fax +1(408) 474-1000 • www.micrel.com Rev 5/16/11 Page 1 PL502-30 750kHz – 800MHz Low Phase Noise VCXO (for 12 to 25MHz Crystals) BLOCK DIAGRAM VCON Varicap XIN XOUT Xtal Osc VCO Divider Reference Divider Phase Detector SEL[3:0] Charge Pump + Loop Filter CLKBAR VCO CLK OE FREQUENCY SELECTION TABLE SEL3 (Pad #28) SEL2 (Pad #29) SEL1 (Pad #19) SEL0 (Pad #20) 0 0 0 0 Reserved 0 0 0 1 Reserved 0 0 1 0 Reserved 0 0 1 1 Fin x 32 0 1 0 0 Reserved 0 1 0 1 Reserved 0 1 1 0 Fin / 8 0 1 1 1 Fin x 2 1 0 0 0 Reserved 1 0 0 1 Fin / 2 1 0 1 0 Fin / 16 1 0 1 1 Fin x 4 1 1 0 0 Fin / 4 1 1 0 1 Fin x 8 1 1 1 0 Fin x 16 1 1 1 1 No multiplication Selected Multiplier All pads have internal pull-ups (default value is 1).

It is assumed that the crystal will be at nominal frequency at this load. If the crystal requires more load to be at nominal frequency, the additional load must be add ed externally. This however may reduce the pull range. 3. Voltage Control Crystal Oscillator PARAMETERS VCXO Stabilization Time * SYMBOL T VCXOSTB CONDITIONS MIN.
