Table schema:
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)?
SQL: SELECT MAX(clock_rate__mhz_) FROM table_name_75 WHERE bandwidth__mb_s_ < 4800 AND bus_width__bits_ < 16
