7 / 11 page LB11872H No.7257-7/11 Continued from preceding page. Pin No. Pin name Function Equivalent circuit 16 CLK Clock input. Low : 0 to 1.0V High : 2.0V to VREG This pin goes to the high level when open. VREG 33k Ω 5k Ω 16 30k Ω 17 LD Phase locked state detection output. This output goes to the on state when the PLL locked state is detected. This is an open-collector output. VREG 17 18 PD Phase comparator output (PLL output). This pin output the phase error as a pulse signal with varying duty.The output current increases as the duty becomes smaller. VREG 18 19 EI Error amplifier in put pin. VREG 300 Ω 19 20 EO Error amplifier output pin. The output current increases when this output is high. VREG 20 300 Ω 40k Ω Continued on next page. |
