LMK00301 Overview
The LMK00301 is a 3-GHz, 10-output differential fanout buffer intended for high-frequency, low-jitter clock and data distribution, and level translation. The input clock can be selected from two universal inputs or one crystal input. The selected input clock is distributed to two banks of five differential outputs and one LVCMOS output.
LMK00301 Key Features
- 3:1 input multiplexer
- Two universal inputs operate up to 3.1 ghz and accept lvpecl, lvds, cml, sstl, hstl, hcsl, or single-ended clocks
- One crystal input accepts 10-mhz to 40-mhz crystal or single-ended clock
- Two banks with five differential outputs each
- LVPECL, LVDS, HCSL, or Hi-Z (selectable per bank)
- LVPECL additive jitter with lmk03806 clock source at 156.25 MHz
- 20 fs RMS (10 kHz to 1 MHz)
- 51 fs RMS (12 kHz to 20 MHz)
- Frequency range
- LVPECL (DC to 3100 MHz)
LMK00301 Applications
- Clock distribution and level translation for ADCs, DACs, multi-gigabit ethernet, XAUI, fibre channel, SATA/SAS, SONET/SDH, CPRI, high-frequency backplanes
