Radiation-Resistant Chip Synthesizer 1288PL1U (developed by ELVIS Corporation)
1288PL1U
 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).

Low noise constant frequency sinthesizer MSFCH-RC
    The module generates the constant frequency (in the range of 1…4 GHz) that is multiple to reference frequency at the output of high-stable quartz resonator.
Technical specifications
Output constant frequency range: 1…4 GHz (customized according to customer needs)
Reference frequency: internal or external
Maximum phase noise level of output signal can be calculated by means of formula:

Lout = Lref + 20·log(Fout ⁄ Fref) + 5 (offset 10 kHz to output frequency)
Lout = Lref + 20·log(Fout ⁄ Fref) + 10 (offset 100 kHz to output frequency)

where
    Lout – output signal phase noise, dBc/Hz
    Lref – reference phase noise, dBc/Hz
    Fout – output frequency
    Fref – reference frequency
Output level: ≥ +13 dBm
Power supply: 12 V
Consumption current: 200 mA (without reference oscillator)
Sizes: 112 × 57 × 25 mm
Example: signal of 2300 MHz is synthesized
Reference signal (100 MHz) phase noise:
   offset 10 kHz: -165 dBc/Hz
   offset 100 kHz: -170 dBc/Hz
   offset 1 MHz: -170 dBc/Hz

Output signal (2300 MHz) phase noise:
   offset 10 kHz: -133 dBc/Hz
   offset 100 kHz: -134 dBc/Hz
   offset 1 MHz: -148 dBc/Hz


MSFCH-RC phase noise performance at 2.3 GHz
