ME15 Magnetic Encoder Manual
Revision 1.1
INT
t
is the time of one interrogation.
M
t
is the time that the Stop bit is valid, which is typically 15 – 20
µ
s.
IDL
t
is the time between the last pulse of
CLK
signal cycle and the first falling edge of the next
CLK
cycle.
DO valid
t
is time between rising edge of
CLK
and data output valid.
Optionally, if only absolute angular position data is needed, then SSI clock with 10 pulses could be used. Data
transmission timing is outlined in Figure 2:
Figure 2
Multiplexing Option
When M15 SSI works as Multiplexing SSI device, all M15’s Data (
DO
) and SSI Clock (
SSI CLK
) lines will be
connected together and each device will have separate Enable (
ENn
) line as it is outlined in Figure 3. Maximum
number of M15 SSI units connected is 32.
