Re: SI4735 and EVK board...
1.) Does the SI4735-D60 variant still support SPI control?
[The -D60 datasheet only discusses I2C & '3-wire', while datasheet for earlier Si4735-C40
variant mentions all *three* control methods: I2C, SPI and 3-wire. ]
2.) For the SI4735 EVK baseboard ("SI47xx BB Rev1.5"), the RCLK selection jumper header (J52)
is missing / unstuffed (along with J57, "DISABLE INT RCLK").
Board apparently uses the 32.768Hz osc (X1) as default. And J52 pads show the center pad is
shorted to "INT_RCLK"....
...So if I want to use external RCLK source via J4 SMA ("Ext RCLK"), do I have to cut any PCB traces/foil??
