PERFORMANCE SPECIFICATIONS

The performance targets defined in this section are for the entire linecard comprised of both chips

in the Intelligent Access voice chipsets unless otherwise noted. Specifications for the individual chips

Intelligent Access™ Voice Chipsets System Target Specifications

Notes:

1. Not tested or partially-tested in production.

2. These numbers are only valid when an ISLIC device operates with an ISLAC device, because the ISLAC

generates the anti-sat feed characteristic. When the Intelligent Access voice chipsets operate in the normal

feed region, the performance is controlled by the ISLIC device. See appropriate ISLIC data sheet for

specific PSRR.
