CMOS
The MC145173 is a single–chip CMOS synthesizer with a four–wire serial
interface for primary use in AM–FM broadcast receivers. The device also finds
use in long–wave (LW) and short–wave (SW) receivers. Two inputs to a single
high–speed N counter are provided, along with 2 phase detectors; one for a
VHF loop up to 130 MHz, and another for an HF loop up to 40 MHz. The VHF
phase detector has a current source/sink output and both detectors feature
linear transfer functions (no dead zones). An external crystal ties across
on–chip circuitry which drives a completely–programmable reference counter.
Thus, a broad range of tuning resolution is possible. The crystal oscillator is
buffered and fed to an open–drain output which is active in the HF mode only.
Due to the patented BitGrabber
registers, address or steering bits are not
needed in the serial data stream for random access of the registers. The serial
port is byte–oriented to facilitate control via an MCU. Tuning across a band is
accomplished with a two–byte transfer to the N register.
The 6–bit analog–to–digital converter (ADC) has two input channels. The
converter is read via a one–byte transfer which includes an end–of–conversion
(EOC) bit.
A 22–stage frequency counter is provided and accepts two IF (intermediate
frequency) signals. Primary use for the frequency counter is for the seek or
scan function on broadcast radio receivers. A proper frequency count ensures
tuning of valid stations on their center frequencies. Reading the count is
accomplished with a three–byte serial transfer which includes a count–com-
plete (CC) bit.
Four general purpose digital outputs are included. One of the outputs is
open–drain; the others are totem–pole (push–pull). Two general purpose digital
inputs are provided also. One input has a comparator with a switch point at 33%
of VDD.
