Key Features
- Four ADCs in a single package, providing a space-saving solution.
- On-chip PLL allows for a single ADC sampling clock, distributing and multiplying it to produce the corresponding data rate clock.
- Coded data rate supports up to 4.0 Gbps per channel, including scrambling for proper dc common mode, embedded clock, and error correction.
- Single 1.8 V power supply operation.
- Flexible synchronization schemes and programmable mode pins.
- On-chip temperature sensor.
- Clock duty cycle stabilizer for high performance across a wide range of clock duty cycles.
- On-chip reference adjustable via SPI control, eliminating the need for external decoupling.
- Various power-down and standby modes supported, with low power consumption (typically 145 mW per channel in standby operation).
Applications
- Communication receivers
- Cable head end equipment/M-CMTS
- Broadband radios
- Wireless infrastructure transceivers
- Radar/military-aerospace subsystems
- Test equipment
