synthesizer/multiplier/divider.

I2C device node required properties:
|
||
|
|
- compatible: shall be "ti,cdce706".
|
||
|
|
- reg: i2c device address, shall be in range [0x68...0x6b].
|
||
|
|
- #clock-cells: from common clock binding; shall be set to 1.
|
||
|
|
- clocks: from common clock binding; list of parent clock
|
||
|
|
handles, shall be reference clock(s) connected to CLK_IN0
|
||
|
|
and CLK_IN1 pins.
|
||
|
|
- clock-names: shall be clk_in0 and/or clk_in1. Use clk_in0
|
||
|
|
in case of crystal oscillator or differential signal input
|
||
|
|
configuration. Use clk_in0 and clk_in1 in case of independent
|
||
|
|
single-ended LVCMOS inputs configuration.
|
||
|
|
|

|
|

|
||
|
|
|
||
|
|
