ORDERING INFORMATION
Order this document by MC145193/D---
The MC145193 is recommended for new designs and offers reduced
power consumption. The counters are programmed via a synchronous serial
port which is SPI compatible. The serial port is byte-oriented to facilitate
control via an MCU. Due to the innovative BitGrabber Plus registers, the
MC145193 may be cascaded with other peripherals featuring BitGrabber
Plus without requiring leading dummy bits or address bits in the serial data
stream. In addition, BitGrabber Plus peripherals may be cascaded with
existing BitGrabber peripherals.
The device features a single–ended current source/sink phase detector A
output and a double–ended phase detector B output. Both phase detectors
have linear transfer functions (no dead zones). The maximum current of the
single–ended phase detector output is determined by an external resistor
tied from the Rx pin to ground. This current can be varied via the serial port.
Slew–rate control is provided by a special driver designed for the REFout
pin. This minimizes interference caused by REFout.
This part includes a differential RF input that may be operated in a
single–ended mode. Also featured are on–board support of an external
crystal and a programmable reference output. The R, A, and N counters are
fully programmable. The C register (configuration register) allows the part to
be configured to meet various applications. A patented feature allows the C
register to shut off unused outputs, thereby minimizing system noise and
interference.
In order to have consistent lock times and prevent erroneous data from
being loaded into the counters, on–board circuitry synchronizes the update
of the A register if the A or N counters are loading. Similarly, an update of the
R register is synchronized if the R counter is loading.
The double–buffered R register allows new divide ratios to be presented
to the three counters (R, A, and N) simultaneously. Maximum Operating Frequency: 1100 MHz @ – 10 dBm Operating Supply Current: 3 mA Nominal at 3.0 V Operating Supply Voltage Range (VDD, VCC, VPD Pins): 2.7 to 5.5 V Current Source/Sink Phase Detector Output:
1.7 mA @ 5.0 V or 1.0 mA @ 3.0 V Gain of Current Source/Sink Phase/Frequency Detector Controllable via
Serial Port R Counter Division Range: 1 and 5 to 8191 Dual–Modulus Capability Provides Total Division up to 262,143 High–Speed Serial Interface: 4 Mbps Output A Pin, When Configured as Data Out, Permits Cascading of
Devices Two General–Purpose Digital Outputs:
Output A: Totem–Pole (Push–Pull) with Four Output Modes
Output B: Open–Drain Patented Power–Saving Standby Feature with Orderly Recovery for
Minimizing Lock Times, Standby Current: 30 μA See App Note AN1253/D for Low–Pass Filter Design, and AN1277/D for
Offset Reference PLLs for Fine Resolution or Fast Hopping
