Functional Description
The CYP15G0401DXA Quad HOTLink II™ Transceiver is a
point-to-point or point-to-multipoint communications building
block allowing the transfer of data over high-speed serial links
(optical fiber, balanced, and unbalanced copper transmission
lines) at signaling speeds ranging from 200-to-1500 MBaud
per serial link. The multiple channels in each device may be
combined to allow transport of wide buses across significant
distances with minimal concern for offsets in clock phase or
link delay.
— COMMA or Full K28.5 detect
— Single or Multi-byte framer for byte alignment
— Low-latency option
• Skew alignment support for multiple bytes of offset
• Synchronous LVTTL parallel input interface
• Synchronous LVTTL parallel output interface
• 200-to-1500 MBaud serial signaling rate
• Internal PLLs with no external PLL components
• Dual differential PECL-compatible serial inputs per
channel
• Dual differential PECL-compatible serial outputs per
channel
Each transmit channel accepts parallel characters in an Input
Register, encodes each character for transport, and converts
it to serial data. Each receive channel accepts serial data and
converts it to parallel data, decodes the data into characters,
and presents these characters to an output register. Figure 1
illustrates typical connections between independent host sys-
tems and corresponding CYP15G0401DXA parts. As a sec-
ond-generation HOTLink device, the CYP15G0401DXA ex-
tends the HOTLink family with enhanced levels of integration
and faster data rates, while maintaining serial-link compatibility
(data, command, and BIST) with other HOTLink devices.
