Part Number: LMK04616 Other Parts Discussed in Thread: LMK04828 , LMK04906 I have an application where I need to halt one of two clocks for a while (during a complex IO reset process) and then bring the clock back synchronously with the other clock (which…
Part Number: LMK04616 I would like to ask for clarification of the use of RESETN. On page 58 of SNAS663B (section 9.5.1) we are told to "Toggle RESETn pin High-Low-High" before programming. I have three related questions:
How long does RESETN…
Part Number: LMK04616 My system based on LMK04616 generates 1000 MHz and 250 MHz clock output is HSDS.
Clock distribution path is PLL2 VCO (= 6 GHz : 3) -> 2 GHz
WCLK = 1GHz (divided by 2)
CLK = 250 MHz (divided by 8)
I am not able to issue 250ps digital…
Part Number: LMK04616 Hi,
I have a custom PCB using LMK04616 and I want to trigger SYSREF pulses on the rising edge of SYNC. I have the SYSREF registers set up correctly because I can trigger SYSREF pulses by setting the GLOBAL_SYSREF bit in GLBL_SYNC_SYSREF…
Part Number: LMK04616 Hello,
When driving the CLKin0 with a singled-ended source with AC-coupling, the datasheet says to set CLKIN0_SE_MODE to 0 so that the component uses the differential buffer mode (P31, 9.3.1.3.2.). When I set it to differential mode…
Hi,
It's good to know, you identified the issue and resolved it.
Regarding your required configuration, attached is the updated config file for default 122.88MHz input reference at CLKin0 input with OSCout_div 10.

Part Number: LMK04616 Hi
As I know, temperature change the delay between ClkinX to ClkoutX.
Question: If I am using two devices, Is it true to say that as the temperature change (same In both devices), the delay from ClkinX to ClkoutX change and move at…
Part Number: LMK04616 Hi,
I'm looking for the jitter and phase noise characteristics of the device when used in clock distribution mode, ie. bypassing PLL1 and PLL2. I only found those characteristics for the dual PLL mode, §7.12 of the datasheet. Did…
Part Number: LMK04616 Hi,
i can see in SNAU222 configuration 4, Device 1 feeds CLKout0 and 1 as a "Continuous SYSREF", while CLKout7 feeds 1 pulse sysref.
However, when looking into TICS PRO and register map, it seems like there is only one…
Part Number: LMK04616 I am using LMK04616 clock gen and am unable to produce a pulsed SYSREF. I can produce a continuous SYSREF but neither pulsed over SPI nor via the SYNC pin has worked so far. I have followed the guidance on the forum here: https://e2e…
