Description
FUNCTIONAL The X R-2120 is a self-contained bandpass fi Iter set designed for realization of Bell 212A compatible 1200 bits/sec PSK modems. The XR-2120 utilizes CMOS technology and switched capacitor circuit techniques to minimize external components to a single crystal or frequency source.
Key Features
- included are digitally programmable transmit and receive gains as well as input anti-aliasing and complete output smoothing filters
- Separate VSS pins for transmit, receive, and digital sections are provided to minimize crosstalk
- The XR-2120 features guaranteed filter group delay specifications, within ±1001lS of nominal
- The XR-2120C is a relaxed version of the X R-2120 with group delay specified within ±15QIlS
