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.

• Maximum Operating Frequency:

  185 MHz @ Vin = 500 mVp-p, 4.5-V Minimum Supply

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.

Features

• Operating Voltage Range: 4.5 to 5.5 V
• Maximum operating frequency: VHFin=130 MHz @ 210 mVp-p, HFin=40 MHz @ 210 mVp-p
