* For the tape and reel option, add -T to the end of the part number. Example: D53G-020.0M-T
Notes:
1. Frequency Calibration; frequency measured at Vcc = 3.3 Vdc, 25°C, referenced to Fo.
2. Frequency stability vs. change in temperature. [± ±Fmaꢀ ꢁ Fminꢂ)2.Fo].
3. Frequency change after reciprocal temperature ramped over the operating range. Frequency measured before and after at 25°C.
4. Within two hours after reflow soldering
5. BW=12K Hz to 20 MHz.
6. Output is DC coupled
