The 570BILF is a PLL-based fanout distribution, spread spectrum clock generator, and zero delay buffer from the ClockBlocks™ series, accepting a clock input and delivering CMOS outputs at frequencies up to 170 MHz. Operating from a 3.15 V to 3.45 V supply, it provides a 1:2 input-to-output ratio with integrated divider/multiplier capability, but no differential I/O — all signals are single-ended CMOS.
Supplied in tube format; the tape-and-reel variant 570BILFT is the same die and electricals, differing only in packaging for automated pick-and-place lines.
No formal second-source cross-reference exists, but the 570BILFT (tape-and-reel) is the direct drop-in equivalent for volume assembly.
