MC145170-1

Description

The new MC145170-1 is pin-for-pin compatible with the MC145170. The MC145170-1 is recommended for new designs.

The MC145170-1 is a single-chip synthesizer capable of direct usage in the MF, HF, and VHF bands. A special architecture makes this PLL the easiest to program in the industry. Either a bit- or byte-oriented format may be used. Due to the patented BitGrabberTM registers, no address/steering bits are required for random access of the three registers. Thus, tuning can be accomplished via a 2-byte serial transfer to the 16-bit N register.

MC145173

Description

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 HF mode only.

MC145190
MC145191

Description

The MC145190 and MC145191 are single-package synthesizers with serial interfaces capable of direct usage up to 1.1 GHz. A special architecture makes these PLLs very easy to program because a byte-oriented format is utilized. Due to the patented BitGrabber TM registers, no address/steering bits are required for random access of the three registers. Thus, tuning can be accomplished via a 3-byte serial transfer to the 24-bit A register. The interface is both SPI and MICROWIRE TM compatible.

Features

MC145192

Description

The MC145192 is a low voltage single-package synthesizer with serial interface capable of direct usage up to 1.1 GHz. A special architecture makes this PLL very easy to program because a byte-oriented format is utilized. Due to the patented BitGrabber TM registers, no address/steering bits are required for random access of the three registers. Thus, tuning can be accomplished via a 3-byte serial transfer to the 24-bit A register. The interface is both SPI and MICROWIRE TM compatible.

MC145220

Description

The MC145220 is a low-voltage, single-chip frequency synthesizer with serial interface capable of direct usage up to 1.1 GHz. The device simultaneously supports two loops. Thw two on-chip dual-modulus prescalers may be independently programmed to divide by either 32/33 or 64/65.

Applications include full-duplex radios, such as UHF cordless and cellular phones. Radio designs requiring two UHF loops or a UHF and VHF loop are accommodated.

MC145200
MC145201

Description

The MC 145200 and MC145201 are single-package synthesizers with serial interfaces capable of direct usage up to 2.0 GHz. A special architecture makes these PLLs very easy to program because a byte-oriented format is utilized. Due to the patented BitGrabber TM registers, no address/steering bits are required for random access of the three registers. Thus, tuning can be accomplished via a 3-byte serial transfer to the 24-bit A register. The interface is both SPI and MICROWIRE TM compatible.
