Pin Description
FUNCTION
Input Rate Select. Connect to TTL low for 2.488Gbps data and to TTL high for 2.67Gbps data.
3.3V Supply Voltage
Positive Serial Data Input
Negative Serial Data Input
PLL Fast Track Control, TTL Input. When FASTRACK is TTL high, the PLL is switched to a fast-
track mode for fast phase acquisition. When FASTRACK is TTL low, the PLL operates normally.
3.3V VCO Supply Voltage
Output Amplitude Mode Select. MODE = OPEN sets the CML output amplitude to high; MODE =
high sets the output amplitude to medium; MODE = low sets the output amplitude to low.
