ZL30158
SyncE and Telecom Rate Clock Translator
Overview
The ZL30158 Synchronous Ethernet Clock Translator, part of Zarlink's ClockCenter platform of Synchronous Clock devices, delivers industry leading synchronization performance for high-speed complex applications. The highly integrated and programmable solution synchronizes to any Telecom or any synchronized Ethernet (SyncE) frequency.
The ZL30158 accepts 2 single ended or differential input references and generates 6 high performance programmable clock outputs. The highly integrated solution allows designers to replace multiple components with a single chip, simplifying design and reducing component count and power.
Applications/Uses
- Clock Generation for Physical Line Interface:
- Synchronous Ethernet, 10 GBASE-R and 10 GBASE-W
- SONET/SDH, OC-192/OC-48
- 100 BaseX, GE, Fibre channel
- Clock Generation and Distribution for back plane Interface:
- TDM, Telecom Bus, Utopia, SBI
- XAUI
Key Features
- Synchronizes to any Telecom (N * 8 kHz) or any Synchronized Ethernet (SyncE) frequency.
- Generates any Telecom or SyncE frequency independent of the input frequency rate
- Uses proprietary DPLL technology to guarantee a stable synchronization path over any combination of input and output ratios and frequencies
- Provides input reference jitter filtering with programmable loop bandwidth in the range of 14 Hz to 896 Hz
- Supports two input references, each configurable as single ended LVCMOS (up to 177.5 MHz) or differential LVPECL (up to 720 MHz)
- Automatic hitless reference switching and stand-by mode on reference fail
- Digital PLL (DPLL) and high speed clock synthesis engine for generating high speed PHY clocks
- Provides four high performance differential LVPECL outputs with maximum speed up to 720 MHz with jitter below 0.7 psec RMS
- Provides 2 high performance single ended LVCMOS outputs with maximum speed of 177.5 MHz with jitter below 1.3 psec RMS
- Operates from a single crystal resonator or crystal oscillator
- Customer defined default configuration, including input/output frequencies, is available via OTP (One Time Programmable) memory
- Configurable using a simple SPI/I2C interface
