As shown in the example below, the switching IC accepts 8 Mbps traffic from the T1 /E1 mezzanine card providing 8 T1 / E1 line service. The traffic is switched between the DSPs and the echo cancellation mezzanine cards (for voice processing) and the backplane. With per-stream rate selection and conversion, the ZL50060 ZL50060 is capable of simultaneously interfacing with the T1/E1 access card running at 8 Mbps, a DSP mezzanine card running at 16 Mbps and an echo cancellation mezzanine card running at 2 Mbps. When a mezzanine card is replaced with a different density card, the data stream rate can simply be re-programmed to the appropriate rate. The ability to support different rates up to 32 Mbps on each input and output stream eliminates the need for external circuitry normally required for rate conversion. Zarlink's ZL50060 ZL50060 further enhances design flexibility, because it is able to interface with a wide range of timing sources. Featuring exceptional jitter tolerance, the device can be timed directly off the backplane's clock and frame pulse signals or from a low cost digital PLL when reference switching or holdover functionality is required. As a result, designers can use the most cost-effective timing architecture for their application. This fully featured switching IC also ensures frame integrity, by providing a low latency of 2 frames constant delay between input and output streams. With per-stream Input delay and Output advancement, the device eliminates the need for glue logic that provides external buffer control when required and aligns data streams. As illustrated, with the industry's widest range of programmable features, the ZL50060 ZL50060 improves flexibility, simplifies design and reduces cost of carrier access equipment.
