Multi-frequency integrated reader solution

Implementing an additional 32-bit ARM CortexM0 microcontroller core, the PRH is an integrated RF Identification reader module for contactless communication at 13.56 MHz and 125 kHz. The package contains three dies: LPC1227FBD48/301, HTRC11001T/02EE, CLRC66301HN1.

The LPC1227 operates at CPU frequencies of up to 33 MHz and include up to 128 kB of flash memory and 8 kB of data memory. The HITAG Reader Chip HTRC110 is intended for use with transponders, which are based on the HITAG silicon (HT1ICS3002x or HT2ICS2002x). And the CLRC663 supports contactless communication and uses MIFARE higher transfer speeds up to 848 kBd in both directions.

4-digit duplex LCD car clock

Designed to drive a 4-digit duplex liquid crystal display (LCD), PCF1175C is a single chip, 4.19 MHz CMOS car clock circuit providing hours, minutes and seconds functions.

The chip contains a time calibration and voltage regulator that are electrically programmable via an on-chip EEPROM. It has also two external single-pole, single-throw switches that accomplish all time setting functions. The circuit is battery-operated via an internal voltage regulator and an external resistor.

Gen1 hex display multiplexer

The CBTL06121 is a six-channel multiplexer designed for Gen1 speeds, at 2.5 Gbit/s for PCI Express or 2.7 Gbit/s for DisplayPort. It provides four differential channels capable of switching or multiplexing (bidirectional and AC-coupled) PCI Express or DisplayPort signals.

CBTL06121 is typically used on motherboards, docking stations or add-in cards where the graphics and I/O system controller chip utilizes I/O pins.The hex display MUX can be used to route the signal from the controller chip, which selects the path to be used by setting a select signal (which can be latched) HIGH or LOW.

Why Used

  • High-bandwidth analog pass-gate technology
  • Very low intra-pair differential skew (< 5 ps)
  • Shutdown mode minimizes power consumption while switching all channels off
  • Very low operation current of 0.2 mA typ
  • Standby mode minimizes power consumption while switching all channels off
  • Single 3.3 V power supply
  • Two pinouts (A and B) available as separate ordering part numbers

Where Used

  • Motherboard applications requiring DisplayPort and PCI Express switching/multiplexing
  • Docking stations
  • Notebook computers
  • Chip sets requiring flexible allocation of PCI Express or DisplayPort I/O pins to board connectors
