Pin Configuration Pin I/O Type Function CLK0, CLK0 Input ECL/PECL Differential reference clock signal input CLK1, CLK1 Input HSTL Alternative differential reference clock signal input CLK_SEL Input ECL/PECL Reference clock input select QA[0–19], QA[0–19] Output ECL/PECL Differential clock outputs VEE(1) 1. In ECL mode (negative power supply mode), VEE is either –3.3 V or –2.5 V and VCC is connected to GND (0 V). In PECL mode (positive power supply mode), VEE is connected to GND (0 V) and VCC is either +3.3 V or +2.5 V. In both modes, the input and output levels are referenced to the most positive supply (VCC). Supply Negative power supply VCC Supply Positive power supply. All VCC pins must be connected to the positive power supply for correct DC and AC operation. VBB Output DC Reference voltage output for single ended ECL and PECL operation Table 2. Function Table Pin 0 1 CLK_SEL CLK0, CLK0 input pair is the reference clock. CLK0 can be driven by ECL or PECL compatible signals. CLK1, CLK1 input pair is the reference clock. CLK1 can be driven by HSTL compatible signals. |
