PCI Express Gen 1/Gen 2 Phy

The TRC5024CPA is a four lane Gen 1 and 2 PCI Express Physical layer (Phy) Phy IP core, delivering high-speed serial data transmission over controlled impedance transmission media such as copper cable, PCB traces or fiber optics. The device offers support for 2.5/5.0 Gbps PCI Express which include spread spectrum clocking, beacon out of band signaling and de-emphasis support. TRC5024CPA operates on 1.2/1.8 V supplies. The IP is capable of transmitting and receiving serial data at 2.5 Gbps and 5.0 Gbps per lane with excellent bit error rate performance.

Each transmit section of the TRC5024CPA contains a low-jitter clock synthesizer, a parallel to serial converter with built in PCS transmit functions, and a CMOS output driver with selectable de-emphasis for use in backplane applications.

Each receive section contains an input limiting amplifier with on-chip terminations and selectable equalization levels, clock/data recovery PLL, and PCS receive functions. Built-in serial and parallel loopback modes. PRBS generator/checker and error detectors aid in support of testing.

The TRC5024CPA requires no external components for its clock synthesizers and clock recovery PLL. Three external resistors are needed to set the proper bias currents for its onchip terminations.

TRC5024CPA has low jitter generation and high jitter tolerance making it ideal for integration in SoCs and ASICs in the presence of multiple clocks and noise. TSMC is available in TSMC 65 nm G process and can be ported to other processes.
