- Fast lock time: 150µs Dual modulus prescaler (64/65) and 2 programmable counters to achieve a feedback division ratio from 4096 to
- Programmable reference frequency divider (9 bits) Phase frequency comparator and charge pump Programmable charge pump current Digital Lock Detector I2C bus interface with 3 bit programmable address (1100A2A1A0) 3.3V Power Supply Power down mode Small size exposed pad VFQFPN28 package 5x5x1.0mm Process: BICMOS 0.35µm SiGe tors (VCOs). Showing high performance, high integration, low power, and multi-band performances, STW81100 is a low cost one chip alternative to discrete PLL and VCOs solutions. STW81100 includes an Integer-N frequency synthesizer and two fully integrated VCOs featuring low phase noise performance and a noise floor of -153dBc/Hz. The combination of wide frequency range VCOs (thanks to center-frequency calibration over 32 sub-bands) and multiple output options (direct output, divided by 2 or divided by 4) allows to cover the 820MHz-1100MHz, the 1640MHz-2200MHz and the 3280MHz-4400MHz bands. The STW81100 is designed with STMicroelectronics advanced 0.35µm SiGe process. * * *
