Fibre Channel Transmitter
CXB1581Q
Description
The CXB1581Q is a transmitter IC with a built-in
PLL for high-speed serial data transmission. It can
be used together with the receiver IC CXB1582Q as
a chip set, and 1062.5Mbaud, 20-bit or 531.25Mbaud,
10-bit operation can be selected.
Features
• Conforms to ANSI X3T11 Fibre channel standard
• Supports GLM (Gigabaud Link Module) interface
• Built-in PLL for synthesizing a low-jitter clock
• Single 3.3V power supply or dual 3.3V/5V power
supply (for 5V TTL interface) operation can be
selected.
• Low power consumption: 830mW (Typ.) when
operating with a single 3.3V power supply
• 1062.5Mbaud, 20-bit or 531.25Mbaud, 10-bit
operation can be selected.
• Test pattern (±K28.5) generation circuit
80 pin QFP (Plastic)
