Jitter cleaner with 14-output fan-out
The Texas Instruments LMK04808BISQE/NOPB is a PLLatinum jitter cleaner that accepts LVCMOS, LVDS, or LVPECL reference inputs and delivers up to 14 differential outputs across the same logic families, with a maximum output frequency of 1.536 GHz. The 2:14 input-to-output ratio lets a single device replace a jitter attenuator plus a clock fan-out buffer, cutting the additive phase noise that comes from cascading separate stages.
1.536 GHz ceiling and I/O flexibility
The 1.536 GHz maximum output frequency covers the reference clock rates for 10 GbE SerDes, JESD204B ADC/DAC converters, and wireless base-station local oscillators. The PLL locks to a clean reference and attenuates the phase noise from the upstream oscillator, so the 14 outputs carry a jitter floor set by the PLL's own loop filter rather than the input source. Each output bank can be independently configured for LVCMOS, LVDS, or LVPECL levels, which means the same IC drives an FPGA SerDes bank (LVDS), a radio-frequency synthesizer (LVPECL), and a system clock monitor (LVCMOS) without external level translators. The differential input-to-output path (Yes/Yes) preserves common-mode rejection across the clock tree.
Listed as Active, so no last-time-buy or allocation risk. The part is in standard production and available through franchised distribution.
