Low-Power, Low-Cost Transceiver Chipset
Part Details
- Single +3.3V Supply
- 495mW Power Consumption
- Exceeds ANSI, ITU, and Bellcore Specifications
- 155Mbps (16-bit wide) Parallel to 2.5Gbps Serial Conversion
- Clock Synthesis for 2.5Gbps
- Multiple Clock Reference Frequencies (155.52MHz, 77.76MHz, 51.84MHz, 38.88MHz)

- Additional High-Speed Output for System Loopback Testing
The MAX3890 serializer is ideal for converting 16-bit-wide, 155Mbps parallel data to 2.5Gbps serial data in ATM and SDH/SONET applications. Operating from a single +3.3V supply, this device accepts low-voltage differential-signal (LVDS) clock and data inputs for interfacing with high-speed digital circuitry, and delivers PECL serial data and clock outputs. A fully integrated PLL synthesizes an internal 2.5GHz serial clock from a 155.52MHz, 77.76MHz, 51.84MHz, or 38.88MHz reference clock. A loopback data output is provided to facilitate system diagnostic testing.
The MAX3890 is available in the extended temperature range (-40°C to +85°C) in a 64-pin TQFP exposed- paddle (EP) package.
