IP-blocks
MALT design center develops digital and analog IPs according to customer requirements. The company’s portfolio includes both Soft IPs and Hard IPs for design of modern VLSI and SoC. IPs are developed for specific technological process of a particular factory according to the requirement specification. Occasionally, we have to develop interface blocks for VLSI integration, when using third-party manufacturers’ IPs.
FDPLL
A programmable fully digital PLL (FDPLL) designed to lock to an incoming clock source and produce an output clock. It is ideal as a clock generator for digital designs, but not intended for analog blocks like ADC / DAC or SERDES clocking. This digital PLL has ultra-low area and low implementation charges due to predictable digital design.

Description
In the capture mode PLL provides periodic signal on CLKO output with period equal to CLKR inputs period multiplied by MULO:EXPO value. Where MULO: EXPO is a denormalized floating-point number, MULO is an 8-bit mantissa, EXPO is a 3-bit exponent. Multiplication coefficient is calculated as follows: the EXPO exponent code [2..0] is interpreted as integer from 0 to 7, which determines the position of the binary point inside the MULO mantissa [7..0]. EXPO numerical value is the number of the MULO digit, followed by a binary dot dividing MULO into integer and fractional parts (the size of the fractional part). For EXPO = 0, the fractional part is absent, and the entire integer part is in MULO [7..0]. For EXPO = 7, the integer part is in MULO [7], fractional in MULO [6..0]. In addition to the main output of the generator, the module has an auxiliary output CLKD, the frequency of which is obtained by dividing the main frequency by a factor of 2*DIVO [4..0].
