Introduction
This application sheet compares the MT9042C
functionality with that of the MT9042B.
The MT9042C is a pin to pin compatible and
functionally enhanced version of the MT9042B.
Most systems currently using the MT9042B will be
able to accept the MT9042C with little or no
modifications to their existing hardware and
software.
Table 1 below illustrates the functional differences
between the two devices. Refer to the MT9042C
datasheet for a detailed functional and electrical
description of the part.

C16 Output Clock Duty Cycle
The C16 output clock duty cycle
depends on the duty cycle of the
20 MHz master clock.
The C16 output clock duty cycle
is 50%, regardless of the duty
cycle of the 20 MHz master
clock.
