MAX1472 Datasheet Crystal-based Ask Transmitter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX1472 19-2872; Rev 4; 6/12 EVAALVUAAILTAIOBNLEKIT 300MHz-to-450MHz Low-Power, Crystal-Based ASK Transmitter.

General Description

The MAX1472 is a crystal-referenced phase-locked loop (PLL) VHF/UHF transmitter designed to transmit OOK/ASK data in the 300MHz to 450MHz frequency range.

The MAX1472 supports data rates up to 100kbps, and adjustable output power to more than +10dBm into a 50Ω load.

The crystal-based architecture of the MAX1472 eliminates many of the mon problems with SAW transmitters by providing greater modulation depth, faster frequency settling, higher tolerance of the transmit frequency, and reduced temperature dependence.

Key Features

  • o 2.1V to 3.6V Single-Supply Operation o Low 5.3mA Operating Supply Current.
  • o Supports ASK with 90dB Modulation Depth o Output Power Adjustable to More than +10dBm o Uses Small Low-Cost Crystal o Small 3mm  3mm 8-Pin SOT23 Package o Fast-On Oscillator 220µs Startup Time.
  • At 50% duty cycle (315MHz, 2.7V supply, +10dBm output power) Ordering Information PART TEMP RANGE PIN- TOP.
