LMK00304  
3-GHz 4-Output Differential Clock Buffer/Level Translator  
Servers, Workstations, and Computing  
1.0 General Description  
The LMK00304 is a 3-GHz 4-output differential fanout buffer  
3.0 Features  
intended for high-frequency, low-jitter clock/data distribution  
3:1 Input Multiplexer  
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 2 differential outputs and  
one LVCMOS output. The differential output banks can be  
mutually configured as LVPECL, LVDS, or HCSL drivers, or  
disabled. The LVCMOS output has a synchronous enable in-  
put for runt-pulse-free operation when enabled or disabled.  
The LMK00304 operates from a 3.3 V core supply and 3 in-  
dependent 3.3 V/2.5 V output supplies.  
Two universal inputs operate up to 3.1 GHz and accept  
LVPECL, LVDS, CML, SSTL, HSTL, HCSL (AC-  
coupled), or single-ended clocks  
One crystal input accepts a 10 to 40 MHz crystal or  
single-ended clock  
Two Banks with 2 Differential Outputs each  
LVPECL, LVDS, HCSL, or Hi-Z (selectable)  
LVPECL Additive Jitter with LMK03806 clock source:  
The LMK00304 provides high performance, versatility, and  
power efficiency, making it ideal for replacing fixed-output  
buffer devices while increasing timing margin in the system.  
20 fs RMS at 156.25 MHz (10 kHz – 1 MHz)  
51 fs RMS at 156.25 MHz (12 kHz – 20 MHz)  
High PSRR: -65 / -76 dBc (LVPECL/LVDS) at 156.25 MHz  
LVCMOS output with synchronous enable input  
Pin-controlled configuration  
2.0 Target Applications  
Clock Distribution and Level Translation for high-speed  
VCC Core Supply: 3.3 V ± 5%  
ADCs, DACs, Serial Interfaces (Multi-Gigabit Ethernet,  
XAUI, Fibre Channel, PCIe, SATA/SAS, SONET/SDH,  
CPRI), and high-frequency backplanes  
3 Independent VCCO Output Supplies: 3.3 V/2.5 V ± 5%  
Industrial temperature range: -40°C to +85°C  
Package: 32-pin LLP (5.0 x 5.0 x 0.8 mm)  
Remote Radio Units (RRU) and Baseband Units (BBU)  
Switches and Routers
