Description
The control microprocessor can send commands to the LC7861KE by setting RWC high and then sending command
I
data synchronized with CQCK. It is also possible to read out the TOC memory data by sending CQCK from the
SQOUT pin by command switching.
I
I
This pin must be set low briefly after power is first applied.
I
O Output pin controllable by serial data sent from the microprocessor.
O 16.9344 MHz output pin
O 4.2336 MHz output pin
O Output pin controllable by serial data sent from the microprocessor.
I
LSI test pin. Normally left open.
I
Chip select pin. The LC7861KE becomes active when this pin is low. (A pull-down resistor is built-in.)

Pin Applications
1. HF signal input circuit; Pin 8: EFMIN, pin 7: EFMO, pin 6: EFMO
An EFM signal (NRZ) with an optimal slice level can be acquired by inputting the HF signal to EFMIN.
2. PLL clock generation circuit; Pin 4: PDO, Pin 3: AI, Pin 2: AO
A VCO can be constructed by combining the LC7861KE with the Sanyo LA9210M. The PDO pin swings in the
positive direction when the VCO phase lags.
