ZL30142GGG2 Descrizione generale
The ZL30142GGG2 from Microchip Technology Inc. is a powerful frequency translator and clock generator IC that caters to the diverse clocking needs of networking and telecommunications applications. With its three independent frequency translation channels, this IC can efficiently translate input clock signals to new output frequencies, ranging from 1 kHz to 710 MHz. Not only does it provide versatile clock distribution capabilities, but it also offers frequency synthesis and jitter attenuation functions to ensure the delivery of high-quality clock signals to downstream components. Its flexible configuration options, accessible via a serial interface, make it easy for users to program the device according to specific clocking requirements. Additionally, the ZL30142GGG2 comes equipped with advanced clocking features such as programmable phase adjustment, clock distribution, and redundancy switching, which collectively contribute to improved system reliability
Caratteristiche principali
- Supports the requirements of ITU-T G.8262 for synchronous Ethernet Equipment slave Clocks (EEC option 1 and 2)
- Supports the requirements of Telcordia GR-1244 Stratum 3 and GR-253, ITU-T G.812, G.813
- Supports ITU-T G.823, G.824 and G.8261 for 2048 kbit/s and 1544 kbit/s interfaces
- Meets the SONET/SDH jitter generation requirements up to OC-48/STM-16
- Synchronizes to telecom reference clocks (2 kHz, N*8 kHz up to 77.76 MHz, 155.52 MHz) or to Ethernet reference clocks (25 MHz, 50 MHz, 62.5 MHz, 125 MHz)
- Generates standard SONET/SDH clock rates (e.g., 19.44 MHz, 38.88 MHz, 77.76 MHz, 155.52 MHz, 622.08 MHz) or Ethernet clock rates (e.g., 25 MHz, 50 MHz, 125 MHz, 156.25 MHz, 312.5 MHz) for synchronizing Gigabit Ethernet PHYs
- Programmable output synthesizer generates telecom clock frequencies from any multiple of 8 kHz up to 100 MHz
- Generates several styles of telecom frame pulses with selectable pulse width, polarity and frequency
- Internal state machine automatically controls mode of operation (free-run, locked, holdover)
- Flexible input reference monitoring automatically disqualifies references based on frequency and phase irregularities
- Provides automatic reference switching and holdover during loss of reference input
- Supports master/slave configuration and dynamic input to output delay compensation for AdvancedTCA
- Configurable input to output delay and output to output phase alignment
