DESCRIPTION OF EACH BLOCK
(1) AMP Block
Radio waves received by the antenna will be amplified by AMP with AGC. Signals output from AMP with AGC
will go through an external quartz resonator, which serves as a band-pass filter, and will be amplified again at
AMP.
(2) AGC Block
Output signals from AMP will be input to the AGC block and the rectifier block. After signals are input to the
AGC block, their high side peak amplitudes are detected. As AGC signals, they will be fed back to AMP with
AGC.
The AGC block has the AGC hold function. When the AGC hold signal is "H," the block performs the regular
AGC operation. The AGC block performs the AGC hold operation when the AGC hold signal is "L."
(3) Rectifier Block
After signals are input to the rectifier block, their high side peak amplitudes are detected. As DET signals, they
will be transferred to the slicer block.

(4) Slicer Block
Signals output from the rectifier block are input to the slicer block and will be shaped to V
DD
as "1" and GND as
"0". Then, these outputs will be output as time codes (TCO).
This LSI has the standby function. When the PON signal is "H," the LSI will perform the regular operation. When
the PON signal is "L," the LSI will be in standby state.
The TCO during the standby state is "H."
(5) Time Code Output
The time code output (TCO) of the ML6190A is in phase with actual time codes input from the antenna. A "H"
level is output for the large amplitude signal and a "L" level is output for the small amplitude signal.

Notes for Mounting the Surface Mount Type Package
The surface mount type packages are very susceptible to heat in reflow mounting and humidity absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name,
package name, pin number, package code and desired mounting conditions (reflow method, temperature and
times).
