VSC7147
VSC7147 and VSC7147-01 - Hex PBC with Dual Repeater/Retimer
FEATURES:
!Industry’s first IC with six Port Bypass Circuits (PBC)
supporting both 1.0625Gb/s and 2.125Gb/s Fibre Channel
data rates – Dual mode provides flexibility by having one
device for new and legacy designs
!Two FibreTimer™ Cells configurable as:
- Repeaters for low latency
- Retimers for true Fibre Channel Compliance
- Reduces external retimer components, provides design
flexibility by allowing mixing and matching of the functions
for design optimization
!Digital design of the FibreTimers produce a device that is well
controlled over voltage, process and temperature variations
Provides a more robust and reliable design
!User-selectable, on-chip receive termination at either 100Ω
or 150Ω
!Speed independent Tx and Rx paths aid in Fibre Channel
Auto-Speed Negotiation – Allows the device to migrate as
the specification evolves
!Device can be strapped for 1 or 2Gb/s operation – Supports
dual speed storage applications
!World-class signal integrity for jitter compliance – Reduces
debug and redesign efforts
!Two digital Signal Detect Units to detect the presence of
valid Fibre Channel encoded serial data - Improves signal
detect reliability
!User selectable Pre-Emphasis on all high-speed outputs -
distorts outputs signal for improved signal driving over long
trace and cable distances
!106.25MHz reference clock
!5V-tolerant LVTTL inputs – Provides design flexibility and
backward compatibility
!Cable equalization on all high-speed inputs – Manages and
corrects signal latency and distortion
!Single 2.5V supply - Reduces wiring complexity
!100-pin, 14mm exposed pad TQFP package - Ideal for compact
JBOD designs
