Table 1 - Functional Differences between the MT9041A and MT9041B
Item
Description
MT9041A
MT9041B
1
Capture range, lock range,
output frequency range.
±
12,600ppm
±
230ppm
2
Phase change slope.
Function of input phase step.
Maximum of 5ns/125us (53ns/
1.326ms)
3
RST pin
TTL type input. All outputs may
be at logic high or logic low or
active when RST at logic low.
Schmitt type input. All outputs
fixed at logic high when RST at
logic low.
4
Pin 8. FP8-GCI frame pulse.
FP8-GCI. This is a 122ns wide
positive frame pulse with the
falling edge aligned with the
center or F0o.
F16o. This is a 61ns wide
negative frame pulse with center
aligned with the center or F0o.
5
Input to output phase alignment
after a reset (TRST or RST).
A function of the reference input
and master clock frequency.
Always aligned. Independent of
the reference input and master
clock frequency.
6
Lock time
3s maximum
30s maximum
7
Loop filter
2.5Hz for E1 and 1.9Hz for T1
1.9Hz for both E1 and T1.
8
C16 duty cycle
Dependant on duty cycle of the
20 MHz clock signal at MCLKi.
45 - 55 % duty cycle independant
of the master clock duty cycle.
9
Jitter tolerance
Exceeds requirements by over
100%.
Exceeds requirements by about
30%.
10
C16o - 16.384Mhz output clock
The clock has a rising edge on
the frame boundary delineated
by the rising edge of F8o.
The clock has a falling edge on
the frame boundary delineated
by the rising edge of F8o.
Introduction
This application sheet compares the MT9041B
functionality with that of the MT9041A.
The MT9041B is an enhanced version of the
MT9041A. Most systems currently using the
MT9041A will be able to accept the MT9041B with
little or no modifications to their existing hardware
and software. Consult the table below to determine
the consequences of substituting devices in your
application.
Table 1 below illustrates the functional differences
between the two devices. For full details on the
MT9041B functionality, refer to the MT9041B data
sheet.
