SCSI Pin Input Characteristics
Active-Low Output Characteristics
Recommended Oscillator and PLL Circuits
R1 = 120 kΩ, R2 = 47 Ω, C1 = 30 pF
Crystal oscillator frequency XTALCK0 = 16.9344 MHz
R3 = 7.5 kΩ, R4 = 200 Ω, R5 = 10 kΩ, C3 = 0.1 µF
C4 = 0.1 µF, C5 = 0.002 µF to 0.01 µF
Note: The values listed above for R3, R4, R5, and C3 also apply when the XTALKC0 frequency is 33.8688 MHz.
Applications must be designed so that the analog V
logic system power supply and is not affected by the logic system power supply fluctuation in any way.
Note: Since the exact values of these components will vary depending on the characteristics of the printed circuit board
Note: Only applies to the active-low output pins DB0 to DB7, REQ, DBPB
