LMK00306 Overview
The LMK00306 is a 3-GHz, 6-output differential fanout buffer intended for high-frequency, low-jitter clock/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 3 differential outputs and one LVCMOS output.
LMK00306 Key Features
- 1 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 a 10 to 40 MHz Crystal or Single-Ended Clock
- Two Banks with 3 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)
- High PSRR: -65 / -76 dBc (LVPECL/LVDS) at 156.25 MHz
- LVCMOS Output with Synchronous Enable Input
LMK00306 Applications
- Clock Distribution and Level Translation for ADCs, DACs, Multi-Gigabit Ethernet, XAUI, Fibre Channel, SATA/SAS, SONET/SDH, CPRI, HighFrequency Backplanes
