■ PIN SETTING

When changing the pin setting, the stabilization wait time for the modulation clock is required. The stabilization

wait time for the modulation clock take the maximum value of “

■ ELECTRICAL CHARACTERISTICS • AC

Characteristics Lock-up time”.

ENS modulation enable setting (MB88151A-100/200/400/500/800)

Note : Spectrum does not spread when “L” is set to ENS. The clock with low jitter can be obtained. Because of ENS

has Pull-up resistance, spectrum spread when “H” is set to it or open the terminal.

XPD Power down setting (MB88151A-101/201/401/501/801)

Note : CKOUT of output pins are fixed to “L” output during power down.

SEL0, SEL1 Modulation rate setting

Note : The modulation rate can be changed at the level of the terminal.
