SaRonix Crystal Clock Oscillator 3.3 & 5V, HCMOS, ACMOS, TTL Technical Data STA / STT Series Frequency Range: Full Size: Half Size: A crystal controlled, low current, low jitter and high frequency oscillator with precise rise and fall times demanded in high performance networking, telecom and processor applications. The tri-state function enables the output to go high impedance. Available in a 14 or an 8 pin DIP compatible, resistance welded, all metal case. Pin 7 (or Pin 4) is grounded to case to reduce EMI. See photo above for new, full size metal package with a true SMD adapter. For this package option select option S in part number builder. Applications & Features • Fibre Channel • Gigabit Ethernet • High performance Processors • True SMD DIL14 version available • High Drive HCMOS, ACMOS or TTL capability • Tri-State output • Precise Rise/Fall Times • Reduced EMI circuitry • Short circuit protected output STA 3.3V 125kHz - 125MHz 500kHz - 125MHz * 1 year @ +40°C Temperature Range: Operating: Storage: 0 to +70°C or -40 to +85°C -55 to +125°C Supply Voltage: Recommended Operating: +5V ±10% or 3.3V ±10% (STA only) Supply Current: 50mA typ, 70mA max @ 5V or 30mA typ, 45mA max @ 3.3V Output Drive: ACMOS / TTL Description STA 5V 125kHz - 135MHz 500kHz - 135MHz ±20, ±25, ±50 or ±100 ppm over all conditions: calibration tolerance, operating temperature, rated input voltage change, load change, aging*, shock and vibration Frequency Stability: ACTUAL SIZE STT 5V 250kHz - 135MHz 250kHz - 135MHz Symmetry: Rise & Fall Times: Logic 0: Logic 1: Load: Period Jitter RMS: Mechanical: Shock: Solderability: Terminal Strength: Vibration: Solvent Resistance: Resistance to Soldering Heat: Environmental: Gross Leak Test: Fine Leak Test: Thermal Shock: Moisture Resistance: See Part Numbering Guide See Part Numbering Guide 10% VDD or 0.5V max 90% VDD or 2.5Vmin 50Ω ACMOS, 95Ω ACMOS @ 3.3V, 50mA sink & source @ TTL 8ps max MIL-STD-883, Method 2002, Condition B MIL-STD-883, Method 2003 MIL-STD-202, Method 211, Conditions B2 MIL-STD-883, Method 2007, Condition A MIL-STD-202, Method 215 MIL-STD-202, Method 210, Condition A, B or C MIL-STD-883, MIL-STD-883, MIL-STD-883, MIL-STD-883, Method Method Method Method 1014, Condition C 1014, Condition A2 1011, Conditions A 1004 Part Numbering Guide STA A 9 9 B 3 - 90.0000 Frequency (MHz) Series STA = ACMOS compatible, 3.3 or 5V STT = TTL compatible, 5V only Symmetry 0 = 40/60% max, 0 to +70°C A = 45/55% max, 0 to +70°C STT to 80 MHz max only STA 3.3V to 109.9999 MHz max only 2 = 40/60% max, -40 to +85°C STA 3.3V to 109.9999 MHz max only Supply blank = 5V (STA or STT, 135MHz max) 3 = 3.3V (STA only, 125MHz max) Stability Tolerance AA = ±20ppm, 80MHz max, 0 to +70°C only A = ±25ppm, 80MHz max, 0 to +70°C only B = ±50ppm C = ±100ppm Standard* Rise/Fall Times 1 = STT 4.0ns max 250kHz to 15 MHz full, to 35 MHz ½ size 2 = STT 2.0ns max from 15+ MHz full, 35+ MHz ½ size to 60 MHz 3 = STT 1.0ns max from 60+ MHz to 135 MHz 7 = STA 5.5ns max, 125kHz to 15 MHz full, 500kHz to 35 MHz ½ size 8 = STA 3.5ns max from 15+ MHz full, 35+ MHz ½ size to 60 MHz 9 = STA 2ns max from 60+ MHz to 135 MHz(5V), to 125 MHz(3.3V) Package Size / Style 0 = Full Size 9 = ½ Size K = Full Size, Gull Wing J = ½ Size, Gull Wing N = ½ Size, Gull Wing, Spanked Leads S = Full Size, True SMD Adapter *R/F times are standard with given frequency ranges, non-standard R/F times available on some models, please contact SaRonix Example PN: STT220C - 60.0000 DS-108 SaRonix REV K 141 Jefferson Drive • Menlo Park, CA 94025 • USA • 650-470-7700 • 800-227-8974 • Fax 650-462-9894 SaRonix Crystal Clock Oscillator 3.3 & 5V, HCMOS, ACMOS, TTL Technical Data STA / STT Series Package Details Output Waveform Tri-State Logic Table FULL SIZE PACKAGE ACMOS 21.0 max .825 0.9 .036 max Tr 5.08 max .200 .46±.08 .018±.003 Tf Pin 7 GND 13.0 .510 max Output Standard Logic LOGIC 1 Logic 1 or NC Oscillation Logic 0 or GND High Impedance 80% VDD 2.5 VDC 1.5 VDC 0.5 VDC LOGIC 0 Pin 1 Tri-State Control Pin 1 Input VDD 20% VDD 15.24±.13 .600±.005 Pin 14 +5 or +3.3 VDC Tr 50% VDD 6.35±.51 .250±.020 (4) Glass Insulators TTL Tf Required Input Levels on Pin 1: Logic 1 = 2.2V min Logic 0 = 0.8V max GND SYMMETRY SYMMETRY Test Circuit TEST POINT 7.75 max .305 Pin 8 Output mA M Pin 14 (8) Marking Format ** Includes Date Code, Frequency & Part Number Pin 8 (5) VCC .01 µF POWER SUPPLY SARONIX XTAL OSC ACMOS 50Ω Load 56Ω OUT OSCILLATOR VM GND 0.01 µF Pin 7 (4) Pin 1 ( 1 )* Denotes Pin 1 TRI-STATE INPUT (current limited on fixture) HALF SIZE PACKAGE 13.0 max .510 *( ) Indicates pin numbers for half-size package 0.9 max .036 .46±.08 .018±.003 Pin 1 Tri-State 1.5 .059 13.0 .510 max 50Ω Ω ACMOS TEST CIRCUIT (5V operation) 5.08 max .200 6.35±.51 .250±.020 7.62±.20 .300±.008 TEST POINT Pin 4 GND mA M Pin 14 (8) 120° 120° 120° 7.62±.20 .300±.008 Pin 14 +5 or +3.3 VDC Pin 5 Output Glass Insulators Pin 8 (5) VCC POWER SUPPLY .01 µF VM ACMOS 95Ω Load 95Ω OUT OSCILLATOR GND Pin 1 ( 1 )* Pin 7 (4) 0.01 µF Marking Format ** Includes Date Code, Frequency & Part Number SARONIX TRI-STATE INPUT (current limited on fixture) *( ) Indicates pin numbers for half-size package 95Ω Ω ACMOS TEST CIRCUIT (3.3V operation) Denotes Pin 1 ** Exact location of items may vary All specifications are subject to change without notice.
