MC68HC05CT4 Rev. 2.0
Dual Phase-Locked Loop (PLL)
11.2 Introduction
This dual PLL is similar to that of the MC145162 60-MHz universal
programmable dual PLL frequency synthesizer. It is especially designed
for CT-1 cordless phone applications.
The PLL features fully programmable 16-bit receive, 16-bit transmit, and
12-bit reference ripple down counters. It also has two independent
phase detectors for transmit and receive loops.
The FinTx and FinRx signals are input to the PLL transmit and receive
counters, respectively. They are typically driven by the loop VCO and
AC-coupled. The minimum input signal level is 200 mVp-p @ 60.0 MHz.
