No.
Two different pulse widths, but the same frequency.
This is down to the available timing sources. Both the channels, on the 877, feed their clock from the same timer (timer 2). In the data sheet, table 8-2, fourth line.
Some atter PWM's (18 family chips), allow two different clocks to be selected.
