ML6190B
Longwave Time Code RF Receiver LSI
FEDL6190B-01
Issue Date: Mar. 3, 2005
GENERAL DESCRIPTION
The ML6190B receives and detects standard low-frequency radio waves and outputs time codes indicating time
and calendar information as digital signals. Using the time codes allows clocks built in various devices to be
corrected automatically. The ML6190B is provided with a built-in antenna switch to allow reception of two radio
frequencies. A CMOS amplifier circuit, which has extremely high impedance input, can capture antenna output
signal voltage effectively, so it can have higher radio wave sensitivity than a bipolar amplifier ciucuit.
Features
⢠High sensitivity (1.0 µVrms typ.)
⢠Low supply current (17 µA typ.)
⢠Low standby current (0.01 µA max.)
⢠Low voltage drive (VDD = 1.1 V to 3.6 V)
⢠Built-in antenna switch (frequency switching)
Functions
⢠RF amplifier
⢠AGC circuit
⢠Rectifier
⢠Slicer
⢠Time code output
⢠Antenna switch
Package
20-pin SSOP (SSOP20-P-44-0.65-K) (ML6190BMB)
