GS6151 Datasheet, PDF (2/77 Pages) Semtech Corporation – Multi-Rate 6G UHD-SDI

The device can operate without an external 27MHz
frequency reference. For applications which require rapid
signal lock, an external 27MHz reference may be used to set
the VCO frequency when not locked to the input signal. The
presence of an external reference crystal is automatically
detected by the device.
In systems that require passing of non-supported data
rates, the GS6151 can be configured to either automatically
or manually enter a bypass mode in order to pass the signal
without reclocking.
A four-wire Gennum Serial Peripheral Interface (GSPI)
facilitates configuration and status monitoring of the
device. Multiple GS6151 devices can be daisy-chained
together with a single 4-pin connection to the host system.
This device is Pb-free, and the encapsulation compound
does not contain halogenated flame retardant. This
component and all homogenous sub-components are
RoHS compliant.
