| OKI Semiconductor 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.

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. AMP with AGC 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." AGC signal (To AMP with AGC) Crystal AGC (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. DET signal (to slicer block) Rectifier 7/11 FEDL6190B-01 OKI Semiconductor ML6190B (4) Slicer Block Signals output from the rectifier block are input to the slicer block and will be shaped to VDD 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." VDD (5) Time Code Output The time code output (TCO) of the ML6190B 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. Antenna Input Signal Time Code Output (TCO) (6) Connecting the Antenna The ML6190B has a built-in antenna switch to allow reception of two receive frequencies. When receiving only one frequency, connect both the antenna and C1 across IN1 and IN2. When receiving two frequencies, add C2 across CSW and IN1 to enable frequency switching.
