com Preliminary Description The SSTX4915 is a low power ASK transmitter IC intended for applications in the North American and European VHF/UHF bands.
The integrated voltage-controlled oscillator (VCO), phase/frequency detector, prescaler, and reference oscillator require only the addition of an external crystal to provide a complete phase-locked loop (PLL).
In addition to the standard power-down mode, the chip also includes an automatic lock-detect feature that disables the transmitter output when the PLL is out-of-lock.
Features Output frequency range: 100 – 960 MHz Supply voltage range: 2.
2 – 3.
6 V Low current consumption with power down capability On-chip VCO with integrated PLL (÷ 64/128) dual modulus prescaler Out-of-lock inhibit circuit SSOP-16 package (0.
