DS2188中文资料T1/CEPT抖动抑制器数据手册ADI规格书

描述 Description

The DS2188 T1/CEPT jitter attenuator chip contains a 128 x 2-bit buffer that, in conjunction with an external 4X crystal, is used to attenuate the incoming jitter present in clock and data. The device meets all of the latest applicable specifications including those outlined in TR62411 (Accunet T1.5 Service Description and Interface Specifications, December 1990), TR-TSY-000170 (Digital Cross-Connect System Requirements and Objectives, November 1985), and the CCITT recommendations G.735 and G.742. The DS2188 is compatible with the DS2180A T1/ISDN primary rate transceiver and DS2181A CEPT transceiver, and is the companion to the DS2187 T1/CEPT receive line interface and DS2186 T1/CEPT transmit line interface. It can also be used in conjunction with the DS2190 T1 network interface unit.
