ECS-3955M-500-B

ECS-3955M SERIES SMD CLOCK OSCILLATOR The ECS-3955M (5V) ia a high capacitive load version of our minature, crystal controlled, low current clock oscillator in an all ceramic SMD package. The low profile package is ideal for PC’s, portable applications and PCMCIA cards. FEATURES • High capacitive load options • Low power consumption • Tri-State Function • Seam welded package • Tape & Reel (1,000 pcs STD) PART NUMBERING GUIDE PACKAGE TYPE ECS-3955M – FREQUENCY (50.0 MHz) 500 – STABILITY TOLERANCE (B=±50 PPM) B Sample Part Number: ECS-3955M-500-B OPERATING CONDITIONS/ELECTRICAL CHARACTERISTICS PARAMETERS FREQUENCY RANGE TEMPERATURE RANGE SUPPLY VOLTAGE FREQUENCY STABILITY* INPUT CURRENT OUTPUT SYMMETRY RISE AND FALL TIMES OUTPUT VOLTAGE LOAD START-UP TIME OUTPUT CURRENT (IOL) (IOL) (IOH) ENABLE/DISABLE TIME Standard Option (B) Option (C) 1.8 ~ 36.0 MHz 36.1 ~ 70.0 MHz @ 1/2 VCC Level VOL VOH HCMOS 1.8 ~ 36.0 MHz 36.0 ~ 70.0 MHz VOL VOH Operating Storage CONDITIONS MIN 1.800 -10 -55˚ +4.5 E CS-3955M (5V) TYP MAX 70.0 +70 +125 +5.5 ±100 ±50 ±25 30 65 60/40 ns VCC x 0.1V 50 5 10 16 -16 ns UNITS MHz ˚C ˚C V DC PPM PPM PPM mA mA % V DC V DC pF ms ms mA mA +5.0 40/60 50 ±4 7 VCC x 0.9V 100 * Inclusive of 25˚C tolerance, operating temperature range, input voltage change, load change, aging shock and vibration. ** An internal pullup resistor from pin 1 to 4 allows active output if pin 1 is left open. Note: A 0.01 µF bypass capacitor should be placed between VCC (Pin 4) and GND (Pin 2) to minimize power line noise.
