General Description
The SY87739L is a complete rate independent frequency
synthesizer integrated circuit. From a single reference
source, this device generates a differential PECL output
frequency from 10MHz up to 729MHz
The SY87739L generates an exactly correct reference
frequency for common data transport protocols. This is
especially important in transponder applications, where a
standards compliant protocol data unit must be generated
downstream, even in the absence of any signal from the
associated upstream interface. In addition, the SY87739L
will generate exactly correct reference frequencies for
common data transport protocols augmented by forward
error
correction
codes.
The
SY87739L
accepts
configuration via a MicroWire interface
For proprietary applications, the SY87739L generates
reference frequencies guaranteed to enable the SY87721L
CDR to lock to any possible baud rate from 28Mbps to
2.7Gbps.
