LVDS/CMOS PHY High Speed SERDES Link

A Multi IO mode for LVDS/CMOS, configurable, low EMI, compliant with TIA/EIA 644-A standards, that is suitable for point-to-point data transmission for automotive and consumer applications.

Microphone Pre-Amplifier

The microphone preamplifier is a low noise, high performance signal processing macro where signal is pre-amplified before it is fed to further processing and a charge-pump for high voltage microphone biasing. This microphone gives clear and good audio quality. Preamplifier has a gain programmability option, which can be used to compensate the variation in microphone sensitivity levels.

10 bit 205Msps Pipeline ADC

High performance CMOS analog to digital converter that digitizes signals at sampling rates upto 205Msps and converts to 10-bits resolution at 205Msps at a very low power of 250mW typical. The reference voltages are internally generated. A power down capability is provided for low power dissipation in stand-by mode. The ADC cell is useful for video and graphics applications.

16 bit sigma delta ADC

High performance CMOS analog to digital converter that digitizes signals of bandwidth upto 20kz can be configured for instrumentation or audio application.

Voltage Controlled Delay Line (VCDL)

Voltage Controlled Delay Line (VCDL) generates precise delay where required delay can be chosen at different output taps based on control bits setting. This delay line gives precise delay at very low power consumption.

Multi-level signal Transmitter

The MCML transmitter is Gigabit, high speed transmitter used in serial communication link. This block enables much smaller transmit swing and hence consumes very low power. Alternatively, this circuit improves bit error rate (BER) significantly by precisely controlling output transmit swing.

Phase Locked Loop 5MHz-100MHz

This IP is a Wide Band CMOS Phase locked loop which generates 5MHz to 100MHz with 14 phases. This PLL is a simple Integer-N based and targeted at High speed SERDES links with different data rate requirements.

Band Gap Reference

This is a Band Gap reference IP for accurate Voltage and Current reference. Targeted voltage of 1.2 V +-2% and Reference Current 20 UA +-10% is generated across Process, Voltage and Temperature.
