Application and Case Diagrams
16 Application and Case Diagrams
16.1 Proposed BiCMOS Modulator Application
Note 1: Cx value depends on crystal characteristics; Cx = 27pF on Motorola application board.
Note 2: Loop Filter components must be as close as possible to pins 14 and 15
Note 3: The 220K pull down resistor set the STBY pin “open” condition to “standby mode”.
Hi/Lo
100nF
Pre-em
If not connected, the “open” condition is “normal mode”
