Combining high performance, high integration, wideband and multi-band capabilities, STMicroelectronics‘ STW8110x RF-synthesizer single-chip family is an alternative to discrete, expensive and bulky PLL and VCO solutions. ST's integrated multi-band RF synthesizers reduce RF BOM and footprint by up to 60% while increasing reliability.
Each component of the STW8110x family includes an integer-N frequency synthesizer and two fully integrated VCOs which feature low phase noise and a noise floor of -154 dBc/Hz. The combination of wide frequency-range VCOs and multiple output options (direct output, divided by two, or divided by four) allows the synthesizers to show multi-band features and frequency coverage up to 4.65 GHz. |

High level of integration: single-chip PLL and VCOs leads to reduced BOM and footprint plus increased reliability |
|
Wideband coverage: only single-chip synthesizers operating
up to 4.65 GHz |
|
Multi-band support: multiple output options enable each
synthesizer to address 1-, 2- and 4-GHz bands |
