Serial Port Characteristics
Serial Port Open Mode
The Serial Port Open Mode features:
a. Compatibility with general serial port protocols that use shift and strobe approach to communication
b. Compatible with HMC PLL with Integrated VCO solutions, useful to address multiple chips of various
types from a single serial port bus.
The Open Mode protocol has the following general features:
a. 3-bit chip address , can address up to 8 devices connected to the serial bus
b. Wide compatibility with multiple protocols from multiple vendors
c. Simultaneous Write/Read during the SPI cycle
d. 5-bit address space
e. 3 wire for Write Only capability, 4 wire for Read/Write capability
HMC RF PLLs with integrated VCOs support Open Mode.
Hittite’s PLL and PLLs with integrated Microwave VCOs products do not support Open Mode.
Typical serial port operation can be run with SCLK at speeds up to 50 MHz
