3.3V AnyClockВ®, 10MHz to 365MHz
Fractional N Synthesizer General Description
The SY87729L is a complete rate independent frequency
synthesizer integrated circuit. From a single reference
source, this device generates a differential PECL
reference frequency for Micrel's SY87721L 10Mbps to
2.7Gbps combined CDR and CMU.
The SY87729L 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, SY87729L will generate exactly correct
reference frequencies for common data transport protocols
augmented by forward error correction codes.
For proprietary applications, the SY87729L generates
reference frequencies guaranteed to enable the SY87721L
CDR to lock to any possible baud rate in its range.
SY87729L accepts configuration via a MicroWireв„ў
