The ZL79238 Next Generation Octal Subscriber Line Audio-processing Circuit (SLAC), in combination with the single channel LE79271 or dual LE79272 SLIC, implements a DSL friendly, high density 8-channel universal telephone line interface with wideband capability. This enables the design of a low cost, high performance, fully software programmable line interface with worldwide applicability. All AC, DC, and signaling parameters are programmable via a microprocessor interface. The ZL792388 has an integrated test tool box which can be used standalone or for high density line cards you can offload a lot of the basic call control and test functions to the LE79124 or LE79128 VCP to help manage calls or resolve faults to the line or line circuit. A full API is available to run on a host processor to simplify software integration.

The ZL792588 Next Generation Octal External Ringing Subscriber Line Audio-processing Circuit (SLAC) device, in combination with the Le79271 SLIC device, implements a high density eight-channel universal telephone line interface with wideband capability for internal or external ringing applications. This enables the design of a low cost, high performance, fully software programmable line interface with worldwide applicability. All AC, DC, and signaling parameters are programmable via a microprocessor interface. **Low Density Chip Set:** Octal SLAC (codec) + Long Loop SLICs [Le792388 (codec)](https://www.microchip.com/wwwproducts/en/LE792388) + [Le79271 (SLIC)](https://www.microchip.com/wwwproducts/en/LE79271) / [Le79272 (Dual SLIC)](https://www.microchip.com/wwwproducts/en/LE79272) [ZL792588 (codec with External/ Internal Ringing)](https://www.microchip.com/wwwproducts/en/ZL792588) + [Le79271 (SLIC)](https://www.microchip.com/wwwproducts/en/LE79271) / [Le79272 (Dual SLIC)](https://www.microchip.com/wwwproducts/en/LE79272)

The ZL80032 is a feature-rich network synchronization solution with two independent DPLL clock channels plus three additional DPLLs for NCO Hybrid, Split XO and redundant oscillator modes, and five extremely low output jitter synthesizers. This solution is ideal for Synchronous Ethernet (SyncE) central timing applications such as 5G Distributed Units (DU), Centralized Units (CU) and Radio Units (CU). The [ZL80732](https://www.microchip.com/wwwproducts/en/ZL80732) is another device in this family which is targeted for 5G SyncE and IEEE1588/PTP timing applications.

The ZL80132B is a feature-rich network synchronization solution with two independent DPLL clock channels plus three additional DPLLs for NCO Hybrid, Split XO and redundant oscillator modes, and five extremely low output jitter synthesizers. Having new features, such as ePPS, fast boot, partial reset, per-input DPLL settings, cascading DPLL and NCO holdover, makes the solution ideal for server-based 5G DU/CU applications,capable of GPS/GNSS synchronization.The part can be used on mother board, M.2 daughter card, OCP daughter card or PCIe daughter card. We also have ePPS Timebuffer [ZL80640B](https://www.microchip.com/en-us/product/ZL80640B) and ePPS buffer [ZL40268](https://www.microchip.com/en-us/product/ZL40268) to form full Timing solution for OCP and traditional 5G networks.

ZL81000 provides two T1/E1/J1 transceivers (transmitters plus receivers) specifically designed for BITS/SSU timing in carrier-class telecommunications equipment. Each transceiver provides full support for T1, E1, J1 and G.703 2048kHz synchronization signals in and out and includes SSM message insertion and extraction. The device also includes two composite clock (CC) receivers and two general-purpose CMOS clock inputs to provide additional support as needed for legacy interfaces. Another part, [ZL81001](https://www.microchip.com/en-us/product/ZL81001) provides a single T1/E1/J1 transceiver to address BITS/SSU Timing applications as well.
