DESIGN NOTES

General

LDT is HIGH when the PLL is unlocked. LDT LDT goes LOW 6.4 ±0.4 ms after these conditions goes HIGH when the communication is no longer apply. See figure l . or when DOT has been HGH for 3.2 us.

Figure l. Lock detector timing

F5K has an internal protective diode to prevent DOT and DOR have 3-state outputs and a.le electrostatic breakdown. The voltage at this pin intended for use with passive lowpass filters. must not exceed VDO. F5K should be left open when not in use.

TYPICAL APPLICATIONS

A                                  with f 10.24 MHz, = 20 arxl CL = 30 PF is recommended.
