2 Owner : SAYD Cypress Confidential Sales Training 3/14/2013 CYPRESS INTERNAL USE ONLY IDT ICS8543 Overview IDT ICS8543 is a high performance fan-out buffer featuring Maximum frequency of 0.8 GHz Additive RMS phase jitter of 0.32 ps Output skew of 40 ps and propagation delay of 2600 ps Supports single ended and multiple differential input standards including LVPECL,LVDS,HSTL,SSTL,CML and HSCL 4 differential LVDS output pairs IDT ICS8543 find applications in: Networking systems Telecommunication systems Storage Infrastructure and Test Equipment IDT ICS8543 accepts wide range of input standards IDT ICS8543

3 Owner : SAYD Cypress Confidential Sales Training 3/14/2013 CYPRESS INTERNAL USE ONLY Challenges using IDT ICS G/100G Enterprise routers have high frequency requirements High speed Enterprise routers utilize I2C Voltage Controlled Oscillators (VCXO) which operate upto frequencies of 945 MHz IDT ICS8543 has a maximum operating frequency of 800 MHz IDT ICS8543 does not support such high frequency requirements 2. Additive noise increases Bit Error Rate (BER) High noise levels in the circuit result in increased errors during bit detection Low additive RMS phase jitter is a critical requirement for enterprise routers IDT ICS8543 has additive RMS phase jitter of ps 3. Propagation delays result in packet loss Delay in propagation of clock signals to PHY circuits result in loss of data at transceiver ports IDT ICS8543 has high propagation delay of 2600 ps CY2DL1504 solves these problems CY2DL1504 has a maximum operating frequency of 1500 MHz supporting higher frequency requirements CY2DL1504 has a very low additive RMS phase jitter of.05 ps resulting in less noise addition to clock signals CY2DL1504 ensures faster signal transmission with propagation delays of less than 480 ps Ethernet routers require high frequency clock distributors CY2DL1504 High Performance Buffer ensures clock signal distribution with least additive noise and low propagation delay Enterprise Routers

5 Owner : SAYD Cypress Confidential Sales Training 3/14/2013 CYPRESS INTERNAL USE ONLY Customer objections to adopting CY2DL1504 over IDT ICS8543 “Previous design was using IDT ICS8543” CY2DL1504 is pin to pin compatible with IDT ICS8543 CY2DL1504 offers better specifications and performance than the IDT ICS8543 “CY2DL1504 does not accept SSTL and HSTL clock input standards” CY2DL1504 accepts LVDS,LVPECL,HSCL,CML inputs which are the most popularly used clock input standards for Enterprise Router applications

6 Owner : SAYD Cypress Confidential Sales Training 3/14/2013 CYPRESS INTERNAL USE ONLY Sales Cautions for CY2DL1504 Cypress has a narrow portfolio in clock distribution Cypress has a limited portfolio of 4 output High Performance Buffers when compared to IDT’s broader portfolio for 4 output fan -out buffers, offering more options to customers Cypress Confidential
