The CDCLVD1208RHDT is a Clock Buffer distributes one of two selectable clock inputs (IN0, IN1) to 8 pairs of differential LVDS clock outputs (OUT0, OUT7) with minimum skew for clock distribution. It can accept two clock sources into an input multiplexer. The inputs can either be LVDS, LVPECL or LVCMOS. It is specifically designed for driving 50R transmission lines. If the input is in single ended mode, the appropriate bias voltage (VAC_REF) should be applied to the unused negative input pin. The IN_SEL pin selects the input which is routed to the outputs. If this pin is left open it disables the outputs (static). The part supports a fail-safe function. It incorporates an input hysteresis, which prevents random oscillation of the outputs in absence of an input signal.
● 2:8 Differential buffer
● Universal inputs accept LVDS, LVPECL and LVCMOS
● Selectable clock inputs through control pin
● 8 LVDS outputs, ANSI EAI/TIA-644A standard compatible
● <300fs RMS in 10kHz to 20MHz low additive jitter
● 45ps Maximum low output skew
● Green product and no Sb/Br
●Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
