SCSI Pin Input Characteristics
Active Low Output Characteristics
Note: Only applies to the active-low output pins DB0 to DB7, REQ, and DBPB
Rise Time Test Circuit
Recommended Oscillator and PLL Circuits
R1 = 120 kΩ, R2 = 47 Ω, C1 = 30 pF
Crystal element oscillator frequency XTALCK0 = 16.9344 MHz
R3 = 7.5 kΩ, R4 = 200 Ω, R5 = 10k Ω, C3 = 0.1 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 in any way.
Since the exact values of these components will vary depending on characteristics of the printed circuit board used and
other factors, consult the manufacturer of the crystal element when designing the oscillator circuit.
