Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_name_75 ( clock_rate__mhz_ INTEGER, bandwidth__mb_s_ VARCHAR, bus_width__bits_ VARCHAR )

### Question ###
Bandwidth (MB/s) smaller than 4800, and a Bus width (bits) smaller than 16 has what highest Clock rate (MHz)?

### Accurate SQL ###

SELECT MAX(clock_rate__mhz_) FROM table_name_75 WHERE bandwidth__mb_s_ < 4800 AND bus_width__bits_ < 16
