Part Number: LMK00334-Q1

Hi Team,

My customer is looking for 2~3ch Clock buffer with TCXO input ( 52Mhz, Clipped Sinewave) for their system.

it is Automotive application.

Please check the LMK00334-Q1 with this spec and recommend other device if it is not enough to meet this spec.

input TCXO : DSB211SP , 52Mhz TCXO, Sinusoidal, (07~0.9Vpp)

Clock out : 2ch ~ ,

SOC input clock spec :

Parameter		Condition	Min.	Typ.	Max.	Unit
Frequency	F_TCXO	25°C		52		MHz
Frequency Tolerance	F_{TCXO_T}	-20°C ~ 85°C	-16		16	ppm
Peak-to-Peak Voltage	V_PP		0.7		1.8	V
Clock Input Transition Time	T_RISE	Max Transition Time (20 % ~ 80 % Max transition time is decided according to Vpp			3 @0.7 Vpp	ns
Clock Input Transition Time	T_FALL	Max Transition Time (20 % ~ 80 % Max transition time is decided according to Vpp			3 @0.7 Vpp	ns
Duty Cycle	D_TCXO		-47	50	53	%
Input Resistance	R_TCXO			10		kohm
Input Capacitance	C_TCXO			4.8		pF
Reference clock phase noise	L_{REFCLK_10 Hz}	Worst PN			-80	dBc/Hz
	L_{REFCLK_100 Hz}	Worst PN			-104	dBc/Hz
	L_{REFCLK_1k}	Worst PN			-130	dBc/Hz
	L_{REFCLK_10k}	Worst PN			-142	dBc/Hz
	L_{REFCLK_100k}	Worst PN			-144	dBc/Hz
	L_{REFCLK_1M}	Worst PN			-144	dBc/Hz

Joey,

Does the SOC have a differential HCSL input or a single ended LVCMOS input? The LMK00334-Q1 outputs an HCSL signal, and if the inputs are single ended as in your diagram, something like the LMK00804B-Q1.

Regards,

Will
