SC3048B Quartz SAW Frequency Stability Fundamental Fixed Frequency Excellent Jitter and Symmetry Rugged, Miniature, Surface-Mount Case Low-Voltage Power Supply (3.3 VDC) This digital clock is designed for use in critical timing applications. Fundamental-mode oscillation is made possible by surface-acoustic-wave (SAW) technology. The design results in low jitter, compact size, and low power consumption. Differential outputs provide a sine wave that is made to drive 50 loads. 444.0 MHz Differential Sine-Wave Clock Absolute Maximum Rating Power Supply Voltage (VCC at Terminal 1) Input Voltage (ENABLE at Terminal 8) Case Temperature (Powered or Storage) Value 0 to +4.0 0 to +4.0 -40 to +85 Units VDC VDC °C SMC-8 Case Electrical Characteristics Output Frequency Q and Q Output Characteristic Absolute Frequency Tolerance from 444.000 MHz Voltage into 50 (VSWR ≤ 1.2) Operating Load VSWR Symmetry Harmonic Spurious Nonharmonic Spurious Q and Q Period Jitter Output (Disabled) No Noise on VCC 200 mVP-P from 1 MHz to fO on Amplitude into 50 VIH VIL IIH IIL tPD VCC ICC TA 1, 3 1, 3 +3.13 0 +3.30 18 RFM SC3048B 444.00 MHz YYWW 3, 9 Sym fO fO VO Notes 1, 2 1, 3 3, 4, 5 3, 4, 6 3, 4, 6, 7 3, 4, 7, 8 3, 9 3 100 VCC-0.1 0.0 3 VCC VCC+0.1 0.20 5 -1 1 +3.47 40 +70 15 Minimum 443.911 0.5 49 Typical Maximum 444.089 ±200 4.5 2:1 51 -30 -60 30 35 75 Units MHz ppm dBm % dBc dBc psP-P psP-P mVP-P K V V mA mA ms VDC mA °C Output DC Resistance (between Q & Q) ENABLE (Terminal 14) Input HI……
