Microchip SY87729LHY-TR

Да

Overview

The SY87729LHY-TR 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 SY87729LHY-TR 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, SY87729LHY-TR will generate exactly correct reference frequencies for common data transport protocols augmented by forward error correction codes.For proprietary applications, the SY87729LHY-TR generates reference frequencies guaranteed to enable the SY87721L CDR to lock to any possible baud rate in its range. SY87729LHY-TR accepts configuration via a MicroWire™ interface.
