Cypress's CYS25G0101DX SONET OC-48 Transceiver is a communications building block for high-speed SONET data communications. It provides complete parallel-to-serial and serial-to-parallel conversions, clock generation, and clock and data recovery operations in a single chip, optimized for full SONET/SDH compliance.
The CYS25G0101DX Evaluation Board is designed for evaluating as well as understanding the characteristics of the CYS25G0101DX SONET/SDH Transceiver. The evaluation board provides the following advantages:
-
Flexible and easy to operate
-
On-board Cypress 120-pin thin quad flat pack (TQFP) CYS25G0101DX SONET/SDH Transceiver
-
Supports LVPECL or HSTL interfaces
-
Dip switch for selecting different diagnostic modes
-
Four diagnostic modes - Diagnostic Loopback mode, Line Loopback mode, Analog Line Loopback mode, and factory TEST0 (Parallel Line Loopback) mode
-
LFI and FIFO_ERR LEDs
-
Onboard oscillator for the REFCLK
-
Supports external clock source for the REFCLK
-
16-bit RxD, 16-bit TxD bus, RXCLK, TXCLKI, TXCLKO interface
-
SMA connectors for CML input and output buffers
-
Separate Banana Jacks for all voltage sources for measuring current individually
