LMK04803BISQ/NOPB

The LMK04803BISQ/NOPB from Texas Instruments is an active, low-noise clock jitter cleaner designed with dual cascaded PLLs and an integrated 1.9-GHz VCO. This device supports 2 input channels and provides up to 14 outputs, with output types including LVCMOS, LVDS, and LVPECL. It operates within a voltage range of 3.15V to 3.45V and maintains functionality across an industrial temperature range of -40°C to 85°C.

Key features include ultra-low RMS jitter performance, with values as low as 111 fs RMS (12 kHz to 20 MHz). The dual-loop PLLatinum architecture incorporates an integrated low-noise crystal oscillator circuit and a holdover mode for when input clocks are lost. It supports automatic or manual triggering and recovery, with a normalized PLL noise floor of -227 dBc/Hz and a phase detector rate up to 155 MHz.

The LMK04803BISQ/NOPB is available in a 64-WQFN package measuring 9mm x 9mm. It supports various output configurations, including 12 programmable LVPECL, LVDS, or LVCMOS outputs, and offers digital delay adjustment in 25 ps steps. The device can handle clock rates up to 1536 MHz and includes multi-mode operation (Dual PLL, Single PLL, and Clock Distribution).

This jitter cleaner is suitable for applications requiring precise clock signal integrity. Its robust design and wide operating temperature range make it a reliable choice for demanding environments. The surface mountable package simplifies integration into various electronic designs.
