Radiation-Resistant Chip Synthesizer 1288PL1U (developed by ELVIS Corporation)
1288PL1U is a high-performance fractional-N PLL IC capable of frequency synthesis up to 6 GHz. It is designed for radar and communication devices that operate in VHF, UHF, L-, P-, S- and C-band.
Rad-hard property of the IC with the total dose up to 100 kRad (Si) makes it optimal for commercial and military space applications.
1288PL1U features 4/5, 8/9 and 16/17 prescalers, delta-sigma modulator, a phase comparator and a charge pump. Reference frequency differential input is LVDS-compatible. Counter values are programmable through either a serial interface (SPI) or directly hard-wired (DIRECT). Serial mode allows chirp signal generation and fast switching between 32 pre-programmed profiles.
Overall performance of 1288PL1U makes it a viable alternative for products such as PE96xx, PE97xx, PE83xx (Peregrine) and ADF4108S (Analog Devices).
