Preliminary
M61545AFP
Serial Data Control Dual Electronic Volume
REJ03F0162-0200
Rev.2.0
Dec 21, 2005
Description
The M61545AFP is a dual channel electronic volume controlled with 2-wire serial data. The built-in reference and
power regulator circuitries allow operation of an electronic volume with less external parts. M61545AFP is able to cater
for large supply voltage range of 4.5 to 15.0V.

Relationship Between Data, Clock
Preliminary
Latch signal is “H”.
D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D11 D12 D13 D14 D15 D16 D17
DATA signal is read at rising edge of CLOCK.

Data Format for “H” & “L”
Latch signal is read at falling edge of CLOCK.
DATA = “L”
DATA =”H”
DATA
CLOCK
For initialization, 2 blocks of identical 18-bit data need to be sent. The 2 blocks of data would set the operation
condition for M61545AFP. This shown in figure below,
DATA
CLOCK
1 st Block of Data
0.2sec
time
2ndBlock of Data
There should be a delay of 0.2 second before the first block of Clock and Data appear. The interval between the 1st
Block of data and the 2nd Block should be 0.2 second as well. This sequence is to ensure proper operation of
M61545AFP due to the wide dynamic voltage range, which M61545AFP is made to cater for.
This format of initialization needs to be done once only during every powering up of M61545AFP.
It recommends to use external mute switch together because it might generate the shock noise during this initial setup
timing.
