Part Number: LMK04906 Hi Team,
I'm using TB_FMCH_DP3 Board and lmk04906 is monunted on TB_FMCH_DP3.
And i want to generate 135M clock(from clkout0 port) to supply reference clock from lmk04906 to gty(gigabit transceiver) on Xilinx VCU118 Board. …
Part Number: LMK04906 Hi Team,
I have a question for LMK04906 microwire timing
I programmed to read back like below sequence.
a. Write 0x1F // register unlocked
b. Write 0x400000 // reset
c. Write 0xA0011F // readback 0xa address
And then i got below…
I resolved my issue
I used xilinx axi quad spi ip and connect port (spi_clk -> uwire_clk, spi_data -> mosi, spi_ss <-> uwire_le)
And i used lmk04906.c (device driver) from microblaze firmware.
And i was successful microwire write to lm…
Part Number: LMK04906 Hi team,
I am using the LMK04906 and found that VCC1, 4, 5, 7,and 9 did not have 3.3V applied while the other VVC pins did. Would that cause the part to fail? The part still does not lock like the evaluation board did with the same…
Part Number: LMK04906 Dear support teams,
I am using TICS Pro (v 1.7.4.0) to configure the LKM04906 clock generator and then export a file with the hex register values.
It seems that the configuration of the LMK04906 within TICS pro has some problems…
Part Number: LMK04906 Hi team If I want to modify the value of the register after the PLL is locked, how do we write it? Need to write twice when input configuration? The example described in the specification is not very clear。
Part Number: LMK04906 Hi team,
Could you give me comment on following customer question?
Q1. As shown in the datasheet table 17, OSCout0 is enabled as EN_OSCout0 = 1, so if the user doesn't change the default setting, VCXO clock will be outputted through…
I have now measured the reference VCXO in-circuit and already did a lot of debugging to improve the in-circuit phase noise of it.
I was able to get very close to the VCXO spec of
1 kHz: -137 dBc/Hz 10 kHz: -158 dBc/Hz 100 kHz: -167 dBc/Hz 1 MHz: - 169 dBc…
Part Number: LMK04906 Hi team, The following settings are made when using LMK04906. (Refer to the "Settings for LMK04906" below.) The following 26 settings are made each time this LMK4906 is actually used. I'm waiting for 10ms waiting time between…
