SY87725L Description
Features The SY87725L is a single chip transceiver for data rates Single 3.3V supply and 1W typ. power consumption up to 2.5Gbps. On the receive side, it includes a 2.5G/1.25G/625Mbps down stream plete clock recovery and data retiming circuit with 1.25G/625M/156Mbps up stream an integrated 4-bit serial-to-parallel data converter.
SY87725L Key Features
- Single 3.3V supply and 1W typ. power consumption up to 2.5Gbps. On the receive side, it includes a
- 1.25G/625M/156Mbps up stream an integrated 4-bit serial-to-parallel data converter. On
- 4-bit Serdes with LVDS interfaces the transmit side, it includes a synthesizer with an
- Serial Data input sensitivity of 30mV typical integrated 4-bit parallel-to-serial data converter
- Training mode for fast lock acquisition The SY87725L receiver has a synthesizer that
- Link Fault Indicator (LFIN: “HIGH” = Locked) generates an internal clock from an externally supplied
- Separate training and MUX synthesizers TTL or PECL REFCLK that can be either 155.52MHz or 77.76MHz. This internal clock
- Loop back function for diagnostics recovery PLL if an absence of transitions on the input
- TTL-CML Translator for MAC-to-Laser diode driver serial data stream prevents normal clock recovery. This burst control e
- Selectable double data rate option for low cost absence of transitions on the ining serial data FPGA/ASIC MAC implementa
SY87725L Applications
- BPON/GPON/GEPON/EPON The serial interface for both the transmit and receive functions feature industry standard high-speed Markets differential CML I/O. The par
- FTTH/FTTP the LVDS inputs. The first bit for the serial-to-parallel conversion can be moved using the RCV_SYNC input. The RCV_SYNC input enables the parallel wo
