3.3GHz to 3.9GHz
Wireless Broadband RF Transceiver
Programmable Registers and
4-Wire SPI-Interface
The MAX2838 includes 32 programmable 16-bit regis-
ters. The most significant bit (MSB) is the read/write
selection bit. The next 5 bits are register addresses.
The 10 least significant bits (LSBs) are register data.
Register data is loaded through the 4-wire
SPI/MICROWIRE?-compatible serial interface. Data at
the DIN pin is shifted in MSB first and is framed by CS .
When CS is low, the clock is active, and input data is
shifted at the rising edge of the clock. During the read
mode, register data selected by address bits is shifted
out to the DOUT pin at the falling edges of the clock. At
CS rising edge, the 10-bit data bits are latched into the
register selected by address bits. See Figure 1 .
