| ECS-500X SERIES TEMPERATURE COMPENSATED OSCILLATOR The ECS-500X temperature compensated oscillator covers a wide frequency range and offers a highly stable output over temperature. An internal trimmer is a standard feature to tune the TCXO to its nominal frequency. FEATURES * Highly stable output over temperature * Wide frequency range * RoHS Compliant (Pb Free) * TTL/CMOS Compatible PART NUMBERING GUIDE "EXAMPLE" ECS - SERIES 500X - FREQUENCY (14.4 MHz) 144 - FREQUENCY STABILITY (B= 5.0 PPM) B OPERATING CONDITIONS/ELECTRICAL CHARACTERISTICS PARAMETERS FREQUENCY RANGE FREQUENCY STABILITY OPERATING TEMPERATURE STORAGE TEMPERATURE INPUT VOLTAGE (VCC) INPUT CURRENT SYMMETRY RISE TIME FALL TIME "0" LEVEL "1" LEVEL OUTPUT LOAD START-UP TIME FREQUENCY ADJUSTMENT 8.0 TO 30.0 MHz 30.0 TO 80.0 MHz at 1.4 VDC Level at 1/2 VCC Level 8.0 TO 30.0 MHz 30.0 TO 80.0 MHz 8.0 TO 30.0 MHz 30.0 TO 80.0 MHz TTL CMOS TTL CMOS TTL CMOS 8.0 TO 30.0 MHz 30.0 TO 80.0 MHz Internal Trimmer CONDITIONS Option A Option B Option C MINIMUM 8.000 -7.0 -5.0 -3.5 -20 -30 4.5 V TYPICAL MAXIMUM 80.000 +7.0 +5.0 +3.5 +70 +80 5.5 V 15 60 60/40 55/45 13 8 11 6 +0.4 +0.5 UNITS MHz PPM PPM PPM C C V DC mA mA % % ns ns ns ns V V V V TTL gates pF ns ns PPM 5.0 V 40/60 45/55 50 4 50 2 +2.4 VCC -0.5 10 15 10 7 5 PACKAGE DIMENSIONS (mm) Pin 1 15.24 0.2 Pin 7 12.8 max 6.3 0.5 Pin 14 7.62 0.2 Trimmer Hole 7.62 1.1 PIN CONNECTIONS #1 N.C. #7 GND #8 OUTPUT #14 +VCC CMOS TTL TR TF VCC Pin 8 1 LEVEL 90% VCC 5.0 20.5 max. 6.35 7.2 max.
