SONET OC-48 operation  
The CYS25G0101DX SONET OC-48 Transceiver is a commu-  
nications building block for high speed SONET data communica-  
tions. It provides complete parallel-to-serial and serial-to-parallel  
conversion, clock generation, and clock and data recovery  
operations in a single chip optimized for full SONET compliance.  
Bellcore and ITU jitter compliance  
2.488 GBaud serial signaling rate  
Multiple selectable loopback or loop through modes  
Single 155.52 MHz reference clock  
Transmit Path  
New data is accepted at the 16-bit parallel transmit interface at  
a rate of 155.52 MHz. This data is passed to a small integrated  
FIFO to allow flexible transfer of data between the SONET  
processor and the transmit serializer. As each 16-bit word is read  
from the transmit FIFO, it is serialized and sent out to the high  
speed differential line driver at a rate of 2.488 Gbits/second.  
Transmit FIFO for flexible data interface clocking  
16-bit parallel-to-serial conversion in transmit path  
Serial-to-16-bit parallel conversion in receive path  
Synchronous parallel interface

LVPECL compliant  
HSTL compliant  
Receive Path  
Ë
As serial data is received at the differential line receiver, it is  
passed to a clock and data recovery (CDR) PLL that extracts a  
precision low jitter clock from the transitions in the data stream.  
This bit rate clock is used to sample the data stream and receive  
the data. Every 16-bit times, a new word is presented at the  
receive parallel interface along with a clock.

The parallel I/O interface supports high speed bus communica-  
tions using HSTL signaling levels to minimize both power  
consumption and board landscape. The HSTL outputs are  
capable of driving unterminated transmission lines of less than  
70 mm and terminated 50transmission lines of more than twice  
that length.

The CYS25G0101DX Transceiver’s parallel HSTL I/O can also  
be configured to operate at LVPECL signaling levels. This is  
done externally by changing VDDQ, VREF and creating a simple  
circuit at the termination of the transceiver’s parallel output  
interface.
