suitable for disk array and FC-AL HUB, etc.
Features
• Conforms to ANSI X3T11 Fibre Channel standard
• Single 3.3V power supply
• Low power consumption: 330mW (Typ.)
• Low jitter
• PLL lock detection circuit
• Port bypass circuit
• Small plastic package (24-pin SSOP)
Applications
• Fibre channel arbitrated loop 1.0625Gbaud HUB
• Disk array

4. SDIN, SDIN∗ inputs
Normally, the VCO performs frequency comparison with the SDIN and SDIN∗ serial data. When there is no
input to SDIN and SDIN∗, frequency comparison is executed with REFCLK. However, the frequency may not
be compared to REFCLK if the noise and others are detected as a signal for no signal state because the both
phases of the ECL differential inputs are internally biased to VBB shown below. As countermeasure to this,
connect either of the differential inputs to VCC via a resistor to generate the voltage difference for the both
phases.
