Pl tronics, Inc.

19013 36th Ave. W, Suite H Lynnwood, WA 98036 USA

Manufacturer of High Quality Frequency Control Products

SM7745D CMOS Series

CMOS with Enable/ Disable, 3rd Overtone Crystal Used

4 Pad 7 x 5mm Leadless Surface Mount Ceramic Clock Oscillator

–

70.00 MHz 170.00 MHz

Low Jitter

Consult factory for higher frequencies

Standard Specifications

Overall Frequency Stability

SM7745D: ± 50 PPM, SM7744D: ± 25 PPM, SM7720D: ± 20 PPM over Operating Temp. Range

Operating Temperature Range 0 to +70 C is standard, but can be extended to - 40 to +85°C for certain frequencies

Supply Voltage (Vcc)

Symmetry (Duty Cycle)

5.0, 3.3, and 2.5 volts available, .01 µF bypass cap recommended, consult factory for 1.8 volts

40/60 to 60/40% is standard, but 45/55% at 50% of Vcc is also available (see Waveform 1)

Logic Levels

Jitter

Logic “1” 90% of Vcc MIN; Logic “0” 10% of Vcc MAX

1 pS RMS maximum, from 12 kHz to 20 MHz from carrier

Output Load

Enable/Disable Option (E/D)

Standard load is 15 pF (typ. 1 ASIC) maximum, see Test Circuit 2 (consult factory for heavier loads)

Output enabled when Pin #1 is open or at Logic “1”; Output disabled when Pin #1 is at Logic “0”.

See Website for Supply Current (Icc) and Rise and Fall Times

Part Numbering Guide

Portions of the part number that appear after the frequency may not be marked on part (C of C provided)

SM77 45 D V - 70.0M - 30 - XXX (Internal Code or blank)

Packaging

Tray or

16mm tape

8mm pitch

Non-Std Output Load

Blank = 15 pF max, 30 = 30 pF max

Model

Frequency in MHz

Frequency Stability

45 = ± 50 PPM

44 = ± 25 PPM

20 = ± 20 PPM

Special Specifications (choose all that apply)

Y: Std Specs (5.0V ± 10%, 0 to +70 C, 40/60% Symmetry)

E: Extended Operating Temperature Range (- 40 to +85 C)

S: 45/55% Symmetry at 50% of Vcc

V: Supply Voltage of 3.3 volts ± 10%

W: Supply Voltage of 2.5 volts ± 5%

X: Supply Voltage of 1.8 volts ± 5% (Consult factory)

Consult factory for available frequencies and specs. Not all options available for all frequencies. A special part number may be assigned.

Frequency Stability is inclusive of frequency shifts due to calibration, temperature, supply voltage, shock, vibration and load
